Cadmium is a soft, low-melting-point metal that has many uses. It is similar in abundance to antimony and bismuth and is the 63d element in order of crustal abundance. Cadmium is associated in nature with zinc (and, less closely, with lead and copper) and is extracted mainly as a byproduct of the mining and processing of zinc.

The cadmium content of the zinc concentrate is usually around 0.3% to 0.5%. An estimated 90% to 98% of the cadmium present in zinc ores is recovered in the mining and beneficiating stages of the extraction process.

Cadmium is produced mainly as a by-product of mining, smelting and refining of zinc and, to a lesser degree, as a by-product of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickel-cadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.

Cadmium (Cd) is a very soft, silvery-white metallic element that can be cut with a knife. 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 is typically produced as a derivative of the processes involved in mining ores of zinc, lead, or copper. Since cadmium is most often found as an impurity in zinc that Stromeyer and Hermann studied, the main source of cadmium is the refining of zinc. A typical one ton sample of zinc led to the production of only 6.5 pounds of cadmium.
Zinc refining is the process of purifying zinc to special high grade (SHG) zinc, which is at least 99.995% pure. This process is not usually required when smelting of zinc is done through electrolysis processes, but is needed when zinc is produced by pyrometallurgical processes, because it is only 98.5% pure.. There are various refining methods, but the refluxing process is the most commonly used.

Feb 10, 2012· Small amounts of cadmium, about 10% of consumption, are produced from recycling sources, mainly from dust generated by recycling iron and steel scrap. Cadmium ore beneficiation process. Low grade Cadmium ore isn't suitable for final applications. It needs to increase the ore grade and reduce the gangue content.
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 corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic.
of phosphate rock mining and processing has occurred at numerous sites around the world over the past few decades. Vertical integration of phosphate rock mining and processing may be a necessary component to compete in the world phosphate fertilizer market when new deposits are developed.
