    Environmental Hazards Of Cadmium Past Present And

    Jan 01, 2019 Cadmium is produced by mining, refining, or smelting of zinc, and is a lesser byproduct of the production of copper and lead (Bi et al., 2006). Therefore, cadmium is produced in relation to zinc, instead of through its direct production. Cadmium production almost doubled from 1950 to 1990, about 20,000 tons annually, while its consumption in ...
