The processing of refractory sulfide black-shale ores and concentrates from the Sukhoy Log deposit containing gold, silver and platinum group metals (palladium and platinum) was investigated. The noble metals were leached both under atmospheric pressure and at 700kPa at 200°C in an autoclave. It was found that the preferred leaching method is the chlorination of the ore in HCl/NaCL solutions in the...
The recovery and separation of cobalt and manganese were investigated according to ion exchanger properties and pH of solutions. It was determined that cobalt sorption increases with pH increase to 5.5. The cobalt and manganese separation is performed using manganese substitution by cobalt ions at pH more than 3.5 on chelating resins ANKB-35 and AMF-2M. The cobalt content of manganese sulphate solutions...
