| titleOfInvention | Processing of sulfidic ores |
| abstract | A process is disclosed that enables a precious metal to be recovered from a sulfidic material. The process is particularly suited to treating single- and double-refractory pyritic materials such as pyrites and arsenopyrites. The process comprises the preparation of an acidic aqueous metal halide solution that has an oxidation potential that is sufficient to oxidise the 5 sulfidic material, with the metal of the metal halide able to function as a multi-valent species during oxidation of the sulfidic material. The sulfidic material is introduced into the acidic aqueous metal halide solution and the oxidation potential is controlled such that the sulfidic material is oxidised, the metal of the metal halide is reduced to a lower valent state, but such that the precious metal is generally not oxidised. The metal of the metal halide is oxidised to a 10 higher valent state, and a residue that comprises the precious metal is separated from the solution for its subsequent recovery. |
