Technology Innovations in the Smelting of Chromite

The increasing costs of electric energy and thus the need to reduce the energy required to produce ferrochrome from 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.

197561&ensp·&enspSMELTING REACTIONS In the smelting process the electric furnace is charged with the chrome ore, a carbon reducing agent, and a flux, usually quartz. Reaction of these materials produces slag and liquid ferrochrome, which are withdrawn from the hearth, and carbon monoxide, which rises through the descending charge.
