Chrome Ores on Ferrochrome Smelting

2015-3-12  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 electricity counts for about 35-40% of total production cost.
