Direct Production of Ferrochrome by Segregation Reduction
A solid reduction process is described whereby chromite is reduced with the help of calcium chloride to produce ferrochrome alloy powders with high metal recovery. The process involves segregation reduction of chromite using graphite as the reductant and calcium chloride as the segregation catalyst. Experiments were performed in the temperature range of 12001400 C to evaluate the

The ore an oxide of chromium and iron is reduced by coal and coke to form an iron-chromium alloy called ferrochrome. The heat for this reaction comes from the electric arc formed between the tips of the electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2 800C. In the process of smelting, over 3 500 kilowatt-hours of electricity are consumed for each ton
