2102791 9222673 PCTABS00018 The invention relates to a process for the treatment of complex metal sulphide materials and for the recovery of metal values from such materials. The process is characterized by first subjecting the material to a leaching process under conditions such that sulphide-sulphur is oxidized to sulphate and such that oxidized iron and impurities such as As will pass into solution, whereafter the leaching residue is melted for conventional pyrometallurgical recovery of the metal values. The invention also relates to the use of different embodiments of the process for recovering the precious metal values from refractory materials containing such values and for recovering metal from complex copper concentrate and complex nickel concentrate.
