Abstract

Diamond is concentrated in raw material, e.g. bort, or waste material, e.g. that produced in the use of diamond tools, by treatment with chlorine or a chlorine compound at 300 DEG -1000 DEG C. Chlorine compounds specified are aluminium, copper, iron, silicon, sulphur, tin, titanium, and zinc chlorides, carbon tetrachloride, dichloroethylene, trichloroethylene, chloroform and phosgene. The material may be pretreated with hydrochloric or nitric acid or alkali metal hydroxide, carbonate, or sulphate followed by washing. The chlorination treatment may be followed by washing with water, acid or alkali.
