process for mining of chromium

Process

At the smelter, charge chrome is produced through a single stage process by smelting a mix of chromite, reductant and fluxes at temperatures in excess of 2000°C Electrical energy, required for the chemical reactions to occur, is supplied to the submerged arc furnaces, through Söderberg electrod.
