Production of cobalt from copper-cobalt ores on the African
Some ores such as those at Mutanda Mining may have a natural source of phosphate in the form of pseudo-malachite Cu 5 PO 4 2 OH 4 which causes the uranium to precipitate in the leaching plant. The addition of phosphoric acid to the leaching circuit reduces the concentration of uranium by about 80% which may be insufficient.
