ABSTRACT:
A process for producing an anolyte and a catholyte for redox cells which comprises the steps of heating chromium ore together with carbonaceous substances to produce a pre-reduced chromium product produced a part of iron and chromium in chromium ore, dissolving the pre-reduced chromium product in hydrochloric acid and/or sulfuric acid iron and chromium. Thus, the dissolving step can be simplified, the predetermined concentration can be simply regulated.
