Process for the recovery of content of chromium from a chromium source carrier

摘要

Chromium values may be recovered from the chromium bearing ores or sources by subjecting the chromium bearing source to a roast in the presence of sulfuric acid and an oxidant which contains manganese compounds at temperatures ranging from about 200 DEG to about 500 DEG C. followed by leaching, separation and solvent or ion exchange extraction whereby chromium is selectively extracted and recovered.
