FIELD: metallurgy.
SUBSTANCE: procedure for separation of metals from waste of fusible alloys consists in electrolysis by anode dissolution of metals of alloy waste in electrolyte melt containing zinc chloride and sodium and potassium chlorides. Also, cathode and anode are separated with a porous diaphragm impregnated with electrolyte. Electrolysis is carried out through a package of diaphragms taken at amount not less, than amount of metal components in alloy. Upon anode dissolution metal-components of alloys in form of alloy-concentrates are alternately taken off each diaphragm. Electrolysis is performed through the package of diaphragms made with layers of porous quartz cloth impregnated with melt of electrolyte of composition (wt %): potassium chloride - 15-20, sodium chloride - 10-15, zinc chloride - the rest.
EFFECT: production of separate crude metals-components of alloy.
