Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries. Besides the ore itself, only a few raw materials are necessary for the refining of lead. The ore concentrating process requires pine oil, alum, lime, and xanthate.

This process uses mechanical energy to deposit metal coatings on small components by the impact of glass beads. Either cadmium or mixedmetal coatings of cadmiumtin or cadmiumzinc can be applied when glass beads, proprietary chemicals, water and metal powder are tumbled with the components in .
Cadmium has many chemical similarities to zinc and is often recovered from the primary zinc ore sphalerite. The single most important use of cadmium is in the production of nickelcadmium (NiCad) batteries. Relation to Mining. Cadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process.

29 Salmon exposed to mining effluent (the wastewater released by a mine) had greater mortality rates, and were generally smaller than unexposed salmon. 30 Some toxic metals such as cadmium and copper can inhibit the olfactory response, the ability of the fish to smell.
Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. Refining of zinc and its cadmium content, can be accomplished by treating the zinc concentrates and/or zincbearing secondary materials using either a hydrometallurgical or pyrometallurgical process.

Cadmium waste streams may also enter the air through () waste combustion and burning of fossil fuels. Because of regulations only little cadmium now enters the water through disposal of wastewater from s or industries. Another important source of cadmium emission is the production of artificial phosphate fertilizers.

Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrat Refining of zinc and its cadmium content, can be accomplished by treating the zinc concentrates and/or zincbearing secondary materials using either a hydrometallurgical or pyrometallurgical process.
Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosionresistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic.
From the above analysis, it is necessary to ensure that the mininginduced fractures do not penetrate into the aquifer, surface water and atmospheric environment in order to reduce the arsenic and cadmium pollution in the process of underground coal gasification.
Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickelcadmium batteries.
