Technology Innovations in the Smelting of Chromite Ore

chromite ore have spurred the innovations in the technologies used for smelting chromite ore. These technologies (Conventional smelting process, Outokumpu process, DC arc route, and Premus process) have been reviewed in this work. Premus process has been found to be the lowest-cost and most energy-efficient ferrochrome smelting
