Abstract

Process for enriching (concentrating) an ore including a plurality of metal sulphides, in which the ore undergoes wet grinding, the pulp obtained next being subjected to treatment and then floatation operations, so as to create a plurality of loose floating particles, each of which is richer in one of the metal sulphides than the initial ore. According to the invention, the grinding operation is performed under an inert protective atmosphere so as to prevent oxidation of the freshly created surfaces during this operation, while the redox potential of the pulp during the conditioning operation is held substantially constant, preferably by injection of nitrogen and/or oxidising gas.
