Abstract:

Sodium sulfide appears to be an inexpensive generally accessible reagent for the settling out of cobalt and nickel from manganese and iron contaminated sulfuric acid solutions, obtained in the process of hydrometallurgical treating of oxidized iron ores and other materials, containing cobalt. The processing of cobalt solutions with sodium sulfide allows to extract into the residue about 94-98 of cobalt and 86-98 of Ni. Settling out of cobalt and nickel with sodium sulfide appears to be a simultaneous operation of cleansing the cobalt from manganese, because the ratio Co Mn changes from 0.1 in solution to 25-35 in concentrate. A technology of applying sodium sulfide for the settling out of cobalt testing under semi-industrial conditions is presented. Author
