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 nickel-cadmium (Ni-Cad) batteries. Relation to Mining. Cadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process.
Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin.

Fortunately, small amounts of cadmium are found in zinc ores and most of the cadmium produced today is obtained as a byproduct of mining and refining zinc. Cadmium is a poisonous metal and its use is somewhat limited for this reason. Like zinc, cadmium can be electroplated to other materials to protect them from corrosion.
Cadmium::minerals, mining, trade, technology projects. Removal of heavy metalswas studied by RUBIO in the adsorptive floatation process for metal ions and dissolved air floatation was employed for the solid/liquid separation and the results showed almost complete removal > 98% of heavy metal ions.
Zinc processing: Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate
Named from the Greek word meaning "calamine", cadmium is a soft, bluishwhite metal. It is soft enough to be cut with a knife. It is an active metal, reacting with air and acids.
