Get PriceCadmium Statistics and Information USGS Cadmium Statistics and Information Cadmium, a soft, malleable, ductile, bluishwhite metal, was discovered in Germany in 1817, and Germany remained the only important producer for 100 years Currently, a large percentage of global cadmium metal production takes place in Asia Cadmium is generally recovered as a byproduct from zinc concentrates
Get PriceCadmium, a soft, malleable, ductile, bluishwhite metal, was discovered in Germany in 1817 and for 100 years Germany remained the only important producer. Greenockite (CdS), the only cadmium mineral of importance, is nearly always associated with sphalerite (ZnS). Consequently, cadmium is produced mainly as a byproduct from mining, smelting, and refining sulfide ores of zinc, and to a lesser ...
