FIELD: hydrometallurgical methods of zinc production; applicable in zinc-electrolyte plants in heap and underground leaching and in processing of mine waters. SUBSTANCE: method of production of cathode zinc includes determination of acid and zinc in initial solution and electrolysis to produce cathode zinc. In so doing, maintained in electrolysis the zinc-sulfuric acid ratio is 1:(1-3) and current density of 450-875 A/sq.m. EFFECT: higher efficiency. 2 cl, 2 tbl
