Using the methods of electron microscopy and IR spectroscopy on the surface of diamonds from the tailings of froth separation, hydrophilic mineral formations have been diagnosed and the efficiency of electrochemical effects has been identified for their removal during processes beneficiation of refractory kimberlites. It is shown that the application of the method of electrochemical conditioning of recycling water in the scheme of flotation of diamond-containing refractory ores makes it possible to clean the surface of diamonds from hydrophilic mineral formations and, accordingly, to increase their recovery into a froth separation concentrate by 5.2% for slightly changed kimberlites and by 23.5% for intensely altered kimberlites.
