FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES

2014-6-28  There are two general types of methods for separating chromium ore (chromite) values from associated gangue minerals by froth flotation techniques. In the first method chromite ore which has been deslimed is subjected to flotation at a pH of 1.5 to 5.5 with a long chain fatty acid collector as reported by Havens (1946). The selectivity of the process is enhanced by adding a soluble fluoride compound such as hydrofluoric acid, sodium fluoride or sodium silicofluoride in the flotation medium. The flotation process is typically conducted by adding 0.5 to 5.0 pounds fatty acid, 0.1 to 10.0 pounds soluble fluoride ion and 1.0 to 11.0 pounds sulfuric acid per ton of ore to the aqueous treatment medium containing the chromite ore.
