017XP-ABS ABSTRACT Metals Recovery Various metals including cobalt nickel and copper can be recovered from a roasted ground ore or waste and particularly from tailings of a pyritic gold ore by leaching with sulphuric acid, oxidising the separated leach liquor, filtering and partially neutralising the liquor. In an improved process, the oxidation is effected with peroxomonosulphuric acid and the neutralisation with a 60:40 to 40:60 mixture of calcium and sodium hydroxide/oxide. By so doing, it is possible to minimise the number of process stages by elimination of either or both solid/liquid separations and to combine the leach and oxidation stage, or to improve the separation of metals from impurities.
