Thus, cadmium is produced mainly as a byproduct of mining, smelting, and refining sulfidic ores of zinc, and, to a lesser degree, lead and copper. Small amounts of cadmium, about 10% of consumption, are produced from secondary sources, mainly from dust generated by recycling iron and steel scrap.
Cadmium: processing; Mining and beneficiation; Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. The mined zinc ores are crushed and ground to liberate the zinc sulfide particles from the waste host rock.

Cadmium Copper Overview. Pure unalloyed copper is soft and ductile, and usually contains approximately 0.7% impurities. Cadmium copper alloys are considered high copper alloys, they contain approximately 98 - 99 % copper, 0.1 - 1.5% cadmium and sometimes minor amounts of other materials.
Abstract. Recovery of cadmium from its low-grade sulfide ore (synthetic solutions) adopting bioleaching process involving the microbe, Acidithiobacillus ferrooxidans, under aerobic conditions is taken up.Leaching rate of cadmium from the ore solutions is examined at various initial loadings of ore solutions, bacterial densities and different pH units and at various temperatures.

Cadmium deposits are documented at "Cinkur Mine." Cadmium is present at a grade sufficient to have a strong effect on the economics of an excavation project. It may even be viable as the only commodity mined. At the time this deposit was surveyed, there was a tapped production. Mining opporations could be year-round, intermittent, or seasonal.
Cadmium Copper. One of the features of copper metallurgy is that copper can be easily alloyed with other metals. The addition of about 1 per cent of cadmium results in an alloy which has a considerably higher tensile strength than electrical grade copper although there is a slight reduction in conductivity.
