chromite smelter process

Technology Innovations in the Smelting of Chromite Ore

In Outokumpu process, the chromite ore is partly reduced in the rotary kiln during preheating, thereby reducing the amount of electric energy required for final smelting of the ore to ferrochrome. Therefore the technology when compared to that of the conventional smelting process saves energy ... Xstrata (2012).Lion Ferrochrome Smelter ...
