Abstract
Four chromites from mines in Montana and California were prereduced to provide suitable charge material for the production of ferrochromium in an electric arc furnace. A part of the Bureau of Mines program investigating technology for efficient and economic recovery of metals from domestic resources, this study has shown that prereduction of these chromites increases productivity and decreases electrical-energy consumption with respect to cases when unreduced materials were used. About 75% chromium metallization and 75% total metallization were realized when high-iron chromites from Montana were prereduced with coal char and coke breeze in a batch rotary kiln. Chromium and total metallizations near 95% were obtained when a metallurgical-grade chromite was prereduced. Satisfactory ferrochromium for the production of stainless steel was produced in an electric arc furnace from all the prereduced materials.
