Cadmium: processing-Metalpedia Commercial grades of cadmium have 99.95%to 99.96% minimum purity, but for special applications such as semi-conductors, grades up to 99.9999% purity are produced by vacuum distillation. Cadmium metal is produced in a variety of shapes such as slabs, ingots and sticks, which are used in alloying, pigments, and in production of cadmium oxide.

Cadmium | Minerals Education Coalition 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

MINERAL COMMODITY PROFILES: CADMIUM - USGS 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.

CADMIUM CONFUSION: Do Consumers Need Protection? Cadmium is used in metal alloys to increase strength, wear resistance, and/or castability, or to lower melting point.

Zinc refining - Wikipedia 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.
