. Various hydrometallurgical processes have been tried to extract nickel and cobalt from these lateritic ores, which involved ammonia-ammonium carbonate leaching [3-4], atmospheric leaching with sulfuric acid[5-7] and high pressure acid leaching[8-10]. High pressure acid leaching is the main process for industrial production of nickel and cobalt with lateritic ore, but it is applicable only......
, Co can be separated with Mn from the solution in Me-OH--S2- system when pH<6. The results provide a theoretical guidance for cobalt and nickel recovery from secondary resources and the preparation of cobalt and nickel products.Key words:complexation-precipitation system; thermodynamics; secondary resources of cobalt and nickel......
