Abstract

The invention relates to a process for separating sulphide-containing materials using hydrogen peroxide. Within the meaning of the invention, sulphide-containing materials are those of natural origin, e.g.
mono or polysulphide ores, or products of industrial processes, e.g.
mining spoil or products of metal smelting.
