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.
Discover here how one of the world''s most renowned manufacturers of large surface mining equipment achieved annual savings of almost 100,000 just by salvaging cylinder head failures – thanks to The SIFCO Process ® in action.
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.
There are many diseases that can come from the pollutants that are released into the air and water during the mining process. For example, during smelting operations large quantities of air pollutants, such as the suspended particulate matter, SO x, arsenic particles and cadmium, are emitted.
