Cadmium

 Cadmium (Synthetic) (Scale: 3 cm)

The main uses of cadmium are as a protective coating to prevent corrosion of steel and in rechargeable nickel-cadmium batteries. Cadmium ore deposits are rare and usually small. However, traces of cadmium are a natural occurrence in phosphates.

Greenockite (CdS) is the only cadmium mineral of economic importance and is nearly always associated with sphalerite (ZnS). Consequently, cadmium is produced mainly as a by-product from the mining, smelting, and refining of sulfide ores of zinc and, to a less extent, lead and copper. There is no record of cadmium production in Victoria.
