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