Abstract

In a method of sorting a particulate mass, eg. diamonds and gangue, according to the oleophilicity of the particles of the mass, the particles (24, 26) of the mass are treated with an oil-containing substance (22) in such a manner that oleophilic particles (24), eg. the diamonds, of the mass are at least partially coated with the substance (22). Next, the particles (24, 26) are exposed to a material (12) having specific properties so that the material adheres to the coated particles (24). Finally, the particles (24, 26) can be sorted according to whether they exhibit the specific properties. The material may comprise an aqueous magnetite suspension and/or air bubbles, so that the particles can be sorted using magnetic separation and/or flotation. <IMAGE>
