Zinc Processing

Secondary Zinc Processing Secondary zinc production uses process scrap from zinc slabs, zinc oxides and zinc dust. Selective melting may also be used to capture zinc if the zinc is mixed with other non-ferrous metals with higher melting points. Zinc is also often recovered from the furnace dust of galvanized steel making plants.
