Similarly, what is Cadmium used for?
Cadmium's major use is in batteries (especially rechargeable nickel–cadmium, NiCad, batteries). As a result of its low coefficient of friction and its high fatigue resistance, cadmium is used in alloys for bearings. Cadmium is used in low melting alloys and is a component of many kinds of solder.
Subsequently, question is, how is cadmium extracted? Pyrometallurgical Process A great deal of cadmium collects with the zinc metal and may be removed by refining of zinc by fractional distillation (the boiling point of cadmium is 767℃ and that of zinc and cadmium metal from zinc concentrates.
