Chrome Ores on Ferrochrome Smelting

Keywords—Ferrochrome production, ferroalloy process optimization, chrome ore I. INTRODUCTION 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 ...

Chromium processing Britannica

In 1898 Hans Goldschmidt, a German chemist, produced pure chromium by the aluminothermic reduction of chromium oxide; the silicothermic process for producing low-carbon ferrochromium was developed in 1907. Chromium metal was produced by electrolysis in 1854, but this method did not find wide commercial acceptance until a century later.
