A B S T R A C T A process for the treatment of nickel-copper concentrates comprises the steps of leaching nickel selectively with a dilute hydrochloric acid solution, separating the leach solution from the residue, roasting the residue at a temperature sufficient to form at least about the stoichiometric quantity of sulphate to convert all the nickel present in the residue to nickel sulphate, leaching the roasted residue with water and precipitating any dissolved copper from the aqueous leach solution thus obtained.
