In the paper the problems of purification of quarry waters from the ions of   heavy metals by the use of electrochemical method are considered. The construction of electrochemical reactor  is described allowing to perform the so-called channel electrolysis at high rate of  liquid flow along of  the electrodes in the conditions of limiting cathode current density (i k ). Technological schemes of complex processing of quarry waters for separation of useful components and estimation of their economic efficiency are presented.
