Abstract

The composition of the surface of natural diamonds in interaction with kimberlite minerals and the aqueous phase in the deposit
and enriched ore is studied. The sequence and conditions for the formation of minerals on the surface of crystals under conditions
of processing of kimberlites have been determined. Confirmed the mechanism of hydrophilization of diamonds comprising crystallization
of hydroxides and oxides of iron as a mandatory initial stage. A method of destruction or subsequent dissolution of minerals
aggregates by the impact of electrolysis products of aqueous systems has been proposed, which allows to restore the hydrophobicity
of diamonds. The use of electrochemically treated water in the froth separation cycle with high diamond recovery made it possible
to increase their recovery in the factory’s concentrate by 8.8%.
