METHOD FOR PREPARING ELECTROLYTE FOR ELECTROLYTIC REFINING OF COPPER Russian patent published in 2006 - IPC C25C1/12 C25D3/38 

FIELD: hydraulic metallurgy of non-ferrous metals, namely electrolytic refining of copper, possibly electroplating metallurgy.

SUBSTANCE: method comprises steps of introducing into electrolyte complex of surface active matters including such as thiocarbomide. The last is preliminarily dissolved in copper sulfate solution at mass relation of ions of copper and sulfur (contained in thiocarbomide) in range 20 - 600 at temperature 40 - 70°C during 10 - 70 h. Initial electrolyte is used as copper sulfate solution for treating thiocarbomide. Invention allows produce smooth cathode copper with high helical elongation characterizing copper capability to rolling.

EFFECT: possibility for producing cathode copper with smooth surface, low content of sulfur, high physical and mechanical properties.
