PROCESS FOR OBTAINING CHROMIUM ENRICHED CHROMITE FROM CHROMITE ORES
摘要
A process for obtaining chromium enriched chromite from chromite ores comprising the steps of: dry chlorinating the ores at a temperature between 400 DEG C and 750 DEG C to produce a chlorinated substrate containing acid soluble ferric oxide, acid soluble ferric chloride and acid insoluble chromium enriched chromite; digesting the chlorinated substrate with hydrochloric acid to dissolve the ferric oxide and the ferric chloride; and recovering the chromium enriched chromite.
