Ferrochrome –silicon is another chromium ferroalloy directly produced from chromite ores by carbothermic reduction in submerged arc furnace. The chromium content ranges from 34 to 42%, that of silicon from 38 to 45%, and that of carbon from 0.05 to 0.06%.
aluminothermic reaction in ferrochrome production
Aug 08, 2018The plant will process alluvial chrome into ferrochrome with a capacity to initially produce 300 tonnes of ferrochrome per month and 600 tonnes at full production. The President added that Government would continue improving the ease of doing business and working closely with the private sector in peace and harmony to rebuild Zimbabwe.
Direct Production of Ferrochrome by Segregation Reduction ...
It was concluded that the addition of calcium chloride not only accelerated the carbothermic reduction of chromite but also promoted the formation and growth of individual ferrochrome alloy particles.
Chrome Ores on Ferrochrome Smelting
IGH carbon ferrochrome (HCFeCr) is produced by carbothermic reduction of chrome ore. Electric power is generally used to supply the energy required to carry out the heating, melting and reduction reactions. The production process is energy intensive, and consumes approximately 3,300-3,800 kWh per ton of metal produced. The cost of

SOME ASPECTS OF THE PRODUCTION OF FERROCHROME …
High-carbon and charge chrome alloys are generally produced in the conventional smelting process by carbothermic reduction of ferrochrome ores using AC submerged-arc and DC open-arc electric furnaces. In AC submerged-arc furnaces, the energy to the furnace is predominantly supplied in a resistive heating mode.
Carbothermic reaction - Wikipedia
A key step in this process is the reduction of sodium sulfate with coal: Na 2 SO 4 + 2 C → Na 2 S + 2 CO 2. The Na 2 S is then treated with calcium carbonate to give sodium carbonate, a commodity chemical. Recently, development of the MagSonic TM carbothermic magnesium process has restarted interest in its chemistry: MgO + C ↔ Mg + CO
