(Signature of Candidate) _______________day of__________________(year)_______________ 2 ABSTRACT A variety of carbonaceous materials are being used for the production of ferrochromium. Reductant materials include carbons such as coal, coke and char. Due to complexity and heterogeneity of carbonaceous reducing materials and a wide range of process requirements, the selection of the most appropriate reducing agent will depend on a number of considerations such as availability of raw material and associated costs, product and process requirements. Matching the correct carbon reductant for each specific process and product requirements has become a vital function of the ferrochrome industry. This selection process however, has become increasingly difficult. In many cases, the substitution of new a reductant, despite being similar in all relevant chemical specification characteristics to previous material, has resulted in different performance properties relative to that expected. An investigation prior to the usage of the substituting reductant in the submerged arc furnace was done in order to obtain required performance properties. The investigation concerned the search for a more reliable model in characterizing the reductant according to their reactivity performance, and using the model parameters to choose the appropriate reductant. The model chosen for this investigation was the Arrhenius model. Sintered chromite ore was reduced with the reductant under investigation in a Thermogravimetric analyzer TGA) at different temperatures. The resultant data was then fitted into the Arrhenius model to obtain the indication of the reactivity of the reductant. The TGA tests suggest that the Vietnamese anthracite has the highest reactivity since its activation energies are the lowest and requires less energy to induce the reductant reaction. The tests also suggest that the rate controlling mechanism is the diffusion of species to the reactive site since the effective diffusion constant is of the order 10-10 to 3 10-11, which is far less than the chemical rate constant of the order 10-6 A generalized rate model developed to describe the reduction of chromite shows that at given particle size and up to a reduction of 40%, the rate of reduction is controlled mainly by interfacial-area chemical reaction, and after which the rate is dominated by diffusion. 4 ACKNOWLEDGEMENT I would like to thank Prof. R.H.

The production is accomplished by simultaneously smelting chromite ore, reductant (char, coal and coke), fluxes (limestone and serpentine) and silica (quartz) in a submerged arc furnace. The electric arc and the electrical resistance of the charge generate the heat required for smelting. The heat is most intense at the electrode tip, and this is where most of smelting reactions occur. The smelting reactions involve the reduction of the metal oxides to the metallic state with the formation of a slag. After the initial heating and subsequent reaction of the charge, the reaction products (ferrochromium and slag) drain to the hearth of the furnace. The metal is tapped into a ladle, and cast into a sandpit from where it is broken into smaller pieces for transport purposes. 1.2 Motivation Coal and coke are the main source of carbon for reduction reactions in the production of ferrochromium. The increasing cost of coke and the fact that suppliers are dwindling, as are the availability of coking coals, leads to consumers in the ferroalloy industry searching for alternative sources of carbon. Such alternatives include char, bituminous coal and anthracite. (Visser, 2000, Hendriktz, Sun, 1997)1. A shortage of good quality South African coking coal has led to significant decrease in the production of coke, suitable for utilisation in submerged arc furnaces, at Iscor?s coking facilities. The shortage of supply resulted in several price increases which, together with possible discontinuation of required quantities, prompted several investigations into alternative coke suppliers (i.e Zimbabwe and China coke) by Assmang 14 Chrome Machadodorp. As a result a number of coke suppliers have been changed over the years since 1996. China nuts coke has been found to complement the operation of the submerged arc furnace in the production of chromium, and have been blended with other reductant in use. In 2003 and 2004, there have been several increase in the cost of China nuts coke, and a decrease in its availability which has led to a higher cost of producing a ton of ferrochromium. This has led Assmang Chrome Machadodorp to look for an alternative cheaper and effective reductant (in terms of chromium recoveries, kg of reductant per ton of metal produced and MW of power consumed per ton of metal produced). 1.3 Objective Previous investigations done only concentrated on the alternative cokes, in this investigation the aim will be to substitute coke with anthracite. Anthracite is relatively cheaper than coke. Although the alternative anthracite might be of similar chemical analysis when compared to China nuts coke, other physical properties (reactivity, resistivity and strength) considered to be important parameters with regard to desirable burden characteristics during the production of high carbon ferrochromium will differ considerably.

This property depends on the type of material, processing conditions, material sizing, operating temperatures and pressures within the furnace mix. High burden resistivity is necessary for good overall heat distribution. It depends on resistivity of the reducing agent, a stable coke bed at the tip of the electrodes, volume fraction of the reductants, carbon content and particle size. Higher resistivity is obtained for the burden where the particle size of the reductant is higher than those of other burden components (Dijs, H.M., Smith, DJ)2. Electrical resistivity is a structure sensitive parameter that reflects the internal structure. Therefore the electrical resistivity of carbonaceous material can be correlated with fraction of ordered carbon and reactivity (Feng, B., Bhatia, S.K. and Barry, J.C.)3. Reactivity of reductants towards reduction of oxides plays an important role in many metal-smelting processes. In general, reactivity decreases with the increase in the degree of graphitisation. In addition, the presence of carbon atoms in the amorphous phase or in aliphatic side chains also leads to an increase in reactivity. The combustion/gasification rate for different reduction materials can therefore be significantly different. As combustion proceeds, reactivity decreases due to loss of volatile matter, enhanced thermal annealing and decreased concentration of active site (Smith, I.W.)4. In addition to structural order, physical characteristics such as pore size distribution and surface area, and composition and concentration of ash impurities present in the carbonaceous material also play an important role. Primary electrical contact between the electrode and charge is through a coke bed and electrical properties of this zone are important as it determines the energy and the temperature distribution in the furnace (Olsen, S.E. and Lindstad, T.)5. 16 2.1 Characterisation of carbonaceous materials Carbonaceous materials are complex systems, which are generally heterogeneous in nature. They exhibit a wide variety of physical and chemical properties and chemical properties. While chemical characteristics control the reactivity of the reductant and influence the amount of reduction material used, product quality and energy consumption in the smelting process, physical properties affect the efficiency and productivity of operation to a certain extent. The main carbonaceous materials used in the production of ferrochrome are mainly coal, coke and char. Coal is composed of mainly carbon, hydrogen, nitrogen, sulphur and inorganic matter. Coal is characterised by its rank, type and grade. Rank characterises the degree of metamorphism of coal and is an important criterion for determining the technological usage of coal. Degree of impurities, maceral composition and calorific value determine the type and grade of coal. Other factors such as texture, porosity, density also affects coal quality. Traditionally, coal selection criteria for ferroalloys production are volatile matter content, ash content, and chemistry and reactivity. Since other reductant material like char and coke are produced from coal their properties will be derived and affected by properties of parent coal material. Char is formed during pyrolysis, that is the first stage of coal combustion, when heated particles are devolatilised yielding a carbon-rich solid residue. Char properties are affected by chemical and physical properties of the parent coal, temperature and time history. Coke is produced by heating coal blend in the absence of oxygen to about 1100oC. Quality and properties of coke are affected by the coal rank, fluidity, maceral and mineral matter composition as well as processing conditions. Traditionally, chemistry, particle size, reactivity and strength after reaction are considered as the most important properties of metallurgical coke for blast furnace operations. Electric arc furnace coke, however, requires higher reactivity, lower strength and proper electrical resistivity. 17 2.2.1 Characterisation technique A variety of analytical tests have been developed to characterize properties of various carbonaceous materials. Many analytical procedure are available around the world from international standards organisations. Basic chemical analysis to determine concentrations of moisture, ash, volatile matter, and fixed carbon, supplemented with elemental analysis are generally performed for a basic characterisation of most carbonaceous materials. Most of mechanical and physical tests used were developed for classifying coals for coke making. These include measurements of specific gravity, free- swelling index, grindability and ash fusion temperature. A reacted coke sample is also used to determine Coke Strength after Reaction (CSR), which is an important property, particularly to blast furnace operations. In the Nippon test a sample is tumbled at 20 rev/min. Tumbling is performed only after extensive reactions with carbon dioxide. CSR is defined as the weight percentage of coke larger than 10 mm in size after 600 revolutions6. Reactivity tests play an important role in the assessment of the quality of reduction materials for metallurgical applications. These are based on the gasification of carbonaceous materials in the presence of some oxidizing gas such as carbon dioxide, oxygen, air or steam. There is no universally accepted standard procedure, but reactivity test of coke towards CO2 developed at Nippon Steel Corporation in Japan in early seventies is widely recognised around the world. In the test, a sample (200g of 20mm particle size) is exposed to CO2 flow for two hours at 1100oC. The percentage of mass loss is referred to as reactivity. In addition to the convectional techniques, characterisation of various carbonaceous materials at an atomic level has gained significance. A number of experimental techniques such as XRD, TEM, SEM, FESEM, and HRTEM supplemented with computer simulations are used nowadays to characterise carbons at an atomic level7. 18 Results obtained from these studies have provided a better understanding of the structure of carbonaceous materials, the evolution after heat treatment and oxidation, and interfacial phenomena. In ferrosilicon production, major gaseous reagent is silicon monoxide. SiO reactivity is the ability of the reducing agent to react with gaseous silicon monoxide at 1650oC to form silicon carbide and carbon monoxide. The SINTEF test8 is based on the volume of SiO gas required by the reducing agent to attain 10% level of CO in off gases. SiO reactivity generally decreases with coal rank. Coke having isotropic carbon forms proved to be more reactive than cokes with anisotropic carbon forms. 2.2 Reaction mechanism in ferrochrome production The Chrome charge to the furnace is principally in the form of lump ore and/or pellets. The lump material consists of chromite grains surrounded by solidified host rock. Pellets are made from chromite concentrates that have been agglomerated and pre-treated to form spherical particles. The grain size and microstructure of the chromites are variable from dense rounded grains in the lump to highly fractured acicular grains in the pellets. The particle size ranges of lump ore, pellets and coke are controlled to maximise bed permeability. The chromite forms part of the spinel crystal family, having the general form (Fe2+,Mg2+)O.(Al3+,Cr3+,Fe3+)2O3. As the charge descends and passes through the reaction zones various reactions occur during metal alloy formation. The mechanisms and kinetics of gaseous reduction of solid South African chromites ore have been studied by a number of workers9. These appears to be general agreement that in the loose charge zone iron is preferentially reduced from the solid chromite grains by reaction with carbon monoxide gas produced in the lower part of the furnace. 19 The rate limiting reaction mechanism during the gaseous reduction of dense chromite grains is the ionic diffusion of metal species in the solid spinel phase. Soykan et al10 proposed that the reduction of chromite occurs by the following sequence: a) Initially Fe3+ and Fe2+ at the surface of the chromite particle are reduced to the metallic state. This is followed by immediately by the reduction of Cr3+ ions to the divalent state. b) Cr2+ ions diffusing toward the centre of the particle reduce the Fe3+ ions in the spinel under the surface of the particle to Fe2+ at the interface between the inner and outer cores. Fe2+ ions diffuse towards the surface, where they are reduced to metallic iron. c) After the iron has been completely reduced, Cr3+ and any Cr2+ that is present are reduced to the metallic state, leaving an iron- and chromium- free spinel, MgAl2O4. The partially altered chromite contains a dispersion of fine iron/chromium metal alloy particles. The solid alloy, formed in the early stage of reduction as the charge descends and is heated through the loose charge zone, is low in chromium. As the reaction time and temperature increases, the chromium concentration in the alloy increases. In the later stages of reduction chromium- iron carbides are observed to form11. The reaction proceeds topochemically, from the surface of the particle in the case of dense ore or from the surface of individual grains for porous materials. In cross section, this compositional variation within a grain is seen in the form of a core of primary spinel surrounded by continuous shell of secondary spinel of variable composition. The composition and thickness of the shell varies with slag composition, temperature, oxygen potential and reaction time. The Fe-Cr alloy forms initially on the outer surfaces of the grains or along microcracks. The rate and extent of reduction of the chromite ore is dependent on the chemical composition of the chromite, grain and particle size, porosity, and temperature history in pre-treatment and in the furnace12. Chromite ores are not uniform in composition; they 20 vary widely with source of material particularly in iron concentration. The relationship between the degree of reduction and the chromium reduction therefore depends on the initial composition. Since the rate limiting reaction mechanism involves solid-state diffusion, diffusion path length is a critical factor determining reaction rate. The ionic flux to the gas/solid interface is inversely proportional to the distance, so that reduction rate is enhanced with decreasing particle and grain size. Even cracks and sub-grains boundaries within the grains enhance the rates of reduction of individual chromite grains. The reduction rates of individual grains in pelletised materials are significantly faster than in lump material because of the smaller grain sizes and the higher porosities of the pellets. The rate of reduction of the chromite can also be influenced by the composition and proportion of matrix material in the particles, since this material fuses and eventually melts as the charge descends through the furnace. The formation of the liquid phase can have multiple effects. If there is a high proportion of matrix material the porosity of the ore, and consequently the ease of reducing gas penetration into the particle, may be diminished. On the other hand the partially reduced spinel may react with and dissolve in the molten slag phase, decreasing the effective particle size and influencing the temperature at which the grains in the chromite particles become dispersed in the bulk. 21 CHAPTER 3: METHOD OF STUDY A common method of test for the reactivity of the reductant (i.e coke or coal) is the exposure of packed bed containing 200g of 20-mm diameter particles to flowing CO2 at 1100oC for 2hours. The percentage mass loss (by the Boudouard reaction) is quoted as the ?coke reactive index? (CRI). While it is feasible to predict and measure the CRI values, it is not obvious what values of these indices are desirable for coke used in ferroalloy production. Given the apparent importance of CO generation (in direct reduction reactions), it appears that a high reactivity would be required. On the other hand, the primary electrical contact between the electrode and the charge is through a coke bed directly beneath the electrode tips. Use of a less reactive coke would presumably favour maintenance of such coke bed. Smaller- sized and more-reactive coke is stated to give higher resistivity (A deWaal, IJ Barker)13. These counteracting requirements perhaps partially explain the general use of a mixture of reductants in ferroalloy production. In this investigation an alternative method of testing for reactivity was utilized. This method involves reducing the sintered chromite ore with a chosen reductant in a Thermo- gravimetric analyser (TGA) at different temperatures. In this method reactivity was redefined as the inherent capacity of the reductant to induce the reduction reactions of the ore or the resistance to the reduction process. A model which is close (or compliment) to this definition was found to be the Arrhenius model : ??? ? ??? ? ??? ? ??? ? ???= o TT TTR E RR o 11 exp [1] where TR and oTR are the rates (in units/sec) at temperature T and oT respectively. E? (J/mol) is the activation energy of the reaction which in this case will be the measure of the capacity of the reductant to induce the reduction reactions of the ore (its reactivity). R (J/(mol.K)) is a gas constant. 22 Previous investigations done by R.H. Eric14 on the solid state reduction of chromite ore suggested that the reaction mechanism of the reduction of the ore involves both the chemical reactions and the diffusion of ionic species (Fe3+, Fe2+, Cr3+, Cr2+, Mg2+, Al3+ and Ti4+) from and to the reaction sites. This has prompted the use of a mixed rate control model to describe the kinetics of the reduction process of the ore: ( ) ( )isii XXt ff PJ 2??? += , mixed rate control [2] ( ) ( ) 3111 ii XX ??=fJ , chemical rate control conversion factor [3] ( ) ( ) ( )iii XXX ?+??= 12131 32fP , diffusion rate control conversion factor [4] *t t=? [5] where : *t is the dimensionless time for a chemical reaction controlled process 2 s? is the ratio of dimensionless time for a chemical reaction controlled process to dimensionless time for diffusion controlled process. iX is the fraction reduction of the sintered ore and was calculated by use of the following equation : oxygenremovableoriginalofmass evolvedCOofMass Xi ? = 999.15 01.28 [6] From equation [2] it follows that : p pp bA VF k ? ?= , chemical reaction rate constant [7] ps p e A kV D 22?= , effective diffusion coefficient [8] where : ? is the density (kgm-3) 23 pF is the shape factor (3 for spherical particles) pV is the volume (m 3) = 3 3 4 r? ( r is the particle radius) pA is the cross sectional area (m 2) = 24 r? ( r is the particle radius) b is the stoichiometric factor ( 4 1 for the reduction of FeCr2O4 spinel) The chemical reaction rate constant ( k , in 1?s ), and the effective diffusion coefficient ( eD , in 1?ms ) obtained at different temperatures are then fitted into the Arrhenius equation [1]. The reactivity of the reductant will then be obtained from the fit of the data to the Arrhenius equation. In order to access the reliability of the method and the data obtained, tests will be done in the arc furnace whereby three different reductants under investigations will substitute the China nuts coke, or be blended with it. The results in terms of Chromium recovery, MW power consumption per ton of metal produced, and kg of ore per ton of metal produced will be correlated to the reactivity values. The stability of the smelter furnace operation will also be closely monitored by monitoring the electrode currents, voltages and the furnace mix resistance. For these tests, 20000 metric tons of each reductant under investigation was ordered. 24 CHAPTER 4: EXPERIMENTAL PROCEDURE Thermogravimetric analyes (TG) was carried out with a Simultaneous Thermal Analyzer STA 409 PC Luxx as shown in figure1. Figure 1: Simultaneous Thermal Analyzer STA 409 PC Luxx. The reaction mixture consisted of sintered chromite ore (chemical analyses given in table 2), and a reductant under investigation. Reductants under investigation were China nuts coke, Argentine coke, Vietnamese anthracite and Springlake anthracite, and their chemical analyses is given in table 3.

The reaction mixture was heated in an alumina sample holder from room temperature to the selected reaction temperature at a heating rate of 10oC per minute, and then held for 120 minutes. The selected temperatures were 1190oC, 1240oC, 1290oC, 1340oC and 1390oC. The furnace was flushed continuously with nitrogen gas at a flowrate of 70Nml.min-1. The mass loss caused by the loss of volatile matter from the reductant and the evolution of CO gas by the reduction reactions was measured continuously by the Simultaneous Thermal analyzer. Literature suggest that the reduction of chromite ore starts around 900oC (M. Honkaniem, H. Krogerus, J. Daavittila and P. Oikarinen)15. The mass loss due to volatiles is calculated from the observed mass loss measured from room temperature till 900oC, and the mass loss due to CO evolution is calculated from the observed mass loss from 900oC till the specified reaction time (i.e. after 120 minutes, at the selected reaction temperature). The percentage reduction at a given time and selected reaction temperature was then calculated by use of equation [6]. 26 CHAPTER 5: EXPERIMENTAL RESULTS The mass of removable oxygen in equation [6] is obtained as follows: The sintered chromite ore contain 30.2% Cr, 17.0% Fe3+, and 2.2% Fe2+. If we consider 100mg of sintered chromite ore, then 30.2mg is Cr, 17.0mg is Fe3+, and 2.2mg is Fe2+. By stoichiometry: 55.845g Fe2+ is contained in 71.844g FeO Then 2.2mg Fe2+ is contained in 2.8303mg FeO Hence oxygen in 2.8303mg FeO = 0.6303mg By stoichiometry: 111.69g Fe3+ is contained in 159.687g Fe2O3 Then 17.0mg Fe3+ is contained in 24.305mg Fe2O3 Hence oxygen in 24.305mg Fe2O3 = 7.305mg By stoichiometry: 103.992g Cr is contained in 151.989g Cr2O3 Then 30.2mg Cr is contained in 44.139mg Cr2O3 Hence oxygen in 44.139mg Cr2O3 = 13.939mg Total mass of removable oxygen = 21.8743mg in 100mg of sintered chromite ore sample. 5.1 Determination of the reactivity of Argentine coke. 199.5 mg of sintered chromite ore and 58.8mg of Argentine coke was used. The mixture contains 20% excess carbon required to react with Cr2O3 and FeO and Fe2O3 in the chromite ore. The reaction mixture was heated in an alumina sample holder from room temperature to the selected reaction temperature at a heating rate of 10oC per minute, and then held for 120 minutes. 27 The selected temperatures were 1190oC, 1240oC, 1290oC, 1340oC and 1390oC. Literature suggest that the reduction of chromite ore starts around 900oC (M. Honkaniem, H. Krogerus, J. Daavittila and P. Oikarinen)15. Hence to compute the fraction reduction of the sintered ore ( iX ) at the selected temperature, a correction should be made to take into account the reduction that occurs from 900oC to the selected temperature. Correlation of the fraction reduction with temperature has been found to be in the form (Y. Yang, Y.

The values of the chemical reaction rate constant and effective diffusion constant were used to determine the relative speed at which the reductants can reduce the chromite ore. The summary of the results of the TGA tests are as follows: Table 12: Summary of the TGA test results.

The TGA tests suggest that the Vietnamese anthracite has the highest reactivity since its activation energies are the lowest and requires less energy to induce the reductant reaction. The reduction of FeCr2O4 by activated carbon in argon atmosphere was studied by C.P.J. Van Vuuren17. The activation energy of the reaction was found to be 197 kJ/mol, which is in good agreement to the activation energy values obtained in the TGA tests. The tests also suggest that the rate controlling mechanism is the diffusion of species to the reactive site since the effective diffusion constant is of the order 10-10 to 10-11, which is far less than the chemical rate constant of the order 10-6. A generalized rate model developed to describe the reduction of chromite shows that at given particle size and up 61 to a reduction of 40%, the rate of reduction is controlled mainly by interfacial-area chemical reaction, and after which the rate is dominated by diffusion7. The tests also suggest that the Vietnamese anthracite is the fastest to react since its effective diffusion constant is high, and Argentine coke being the less reactive and slowest to react (highest activation energy and lowest effective diffusion constant). 62 CHAPTER 7: CONCLUSION The TGA tests suggested that the Vietnamese anthracite has the highest relative reactivity followed by China nuts coke only. Since the rate controlling mechanism is diffusion of species to the reactive site, then Vietnames anthracite is the fastest to react followed by China nuts, and Argentine coke being the slowest to react. Tests were also conducted in the smelter furnace to determine if the performance of the reductant is with accordance to the TGA tests analysis. In performing these tests, 10 to 30% (in terms of fixed carbon) of China nuts being used in the furnace was substituted with the reductant under study. Another test was carried out whereby the China nuts coke was completely substituted with Argentine coke. The sizing of the material was kept at -40+10mm. Due to management of the company considering these tests as their competitive advantage, the tests were considered highly confidential. The publishing of the data of the smelter furnace operation during these tests was not approved. Overall the results of the tests done in the smelter furnace were in good agreement to those obtained in the TGA tests. Hence the TGA test can be used to determine the reactivity of the reductant to a higher degree of confidence. The values of the chemical rate constant and effective diffusion constant obtained in the TGA tests can be used in deciding on the material size to be used, especially when one wants to maintain a stable coke bed underneath the electrodes. Follow-up tests involving the resistivity of the reductant will have to be done to establish the total performance of the reductant and its usability. Overall, the investigation showed that anthracite has a significant potential to substitute coke as a reductant of choice. This is also supported by the fact that anthracite is used as one of the raw material in the production of a submerged arc furnace electrode paste. 63 CHAPTER 8: REFERECES 1.
