An investigation into the leachingics of

A method for the extraction of cobalt from cobalt arsenic sulfide cobaltite ores or concentrates has been identified. The method utilizes an atmospheric oxygen acidic ferric sulfate leach, at temperatures up to 373 K 100°C, to place the cobalt in solution. Extraction of 80 pct of the cobalt was obtained within 24 h and the tests indicate that greater and more rapid extractions are possible.
