Secondary zinc production uses process scrap from zinc slabs, zinc oxides and zinc dust. Selective melting may also be used to capture Primary And Secondary Processing Of Zinc
The development of process routes for the treatment of both primary and secondary sources of zinc has been hindered by the very stringent requirements for production of high-purity zinc by electrowinning (EW). Zinc EW from sulphate medium is extremely sensitive to the presence of trace impurities and requires a highly purified electrolyte.
