Stripping is accomplished using spent electrolyte from the zinc electrowinning. The purified zinc electrolyte containing 50– 60 g/l zinc, 20 ppm iron, 30 ppm chloride and less than 1 ppm of metallic impurities such as copper, cadmium, cobalt and arsenic is produced. Subsequently, 99.99% electrolytic zinc metal is produced.
