secondary zinc production

AP-42, CH 1214: Secondary Zinc Processing- secondary zinc production ,Zinc vapor is condensed and recovered in several forms, depending upon temperature,Flux emissions may be minimized by using a nonfuming flux In production requiring special fluxes that do generate fumes, fabric filters may be used to collect emissions , SECONDARY ZINC SMELTINGa Operation Emissions EMISSION FACTOR RATINGZinc - USGS Mineral Resources ProgramZinc metal production rose in 2012 owing mostly to increased secondary zinc production from a smelter in Pennsylvania, which began sourcing higher quality raw materials in the first quarter, and subsequently improved zinc ,.
