Abstract

A process for producing chromium/chromiumalloys from low-grade chromium-bearing ore (or wastes) yields carbon-free chromium/chromium alloys by fused-salt electrolysis in the presence of reverse-polarity transferred-arc thermal plasma. Reverse-polarity transferred-arc thermal plasma is when the torch itself works as the anode and the molten bath, comprising liquid slag beneath which is reduced metal, thereby forming the cathode of the electrical circuit. Reduction takes place without the use of reductants, so there are no carbon-containing off gases. Through this process, chromic oxide can be reduced to chromium by adjusting the chemical composition of the electrolytic bath. Depending on the metal oxide fed into the bath, a variety of final metal compositions can be produced, such as chromium/chromium alloys.
