Description. Named from the Greek word meaning “calamine,” cadmium is a soft, bluish-white metal. It is soft enough to be cut with a knife. It is an active metal, reacting with air and acids. Cadmium is used in low-melting alloys, especially solder.
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.
Part of the Minerals Edu ion Coalition’s mission is to inform and edu e the general public about the importance of mining in their everyday lives. MEC staff and volunteers staff in-person events, and MEC provides virtual edu ional materials for online events.

Primary cadmium metal is recovered as a byproduct of zinc leaching from roasted concentrates, mainly from the ore mineral sphalerite. Secondary cadmium metal is recovered from spent nickel-cadmium batteries and other
Today, according to the Minerals Edu ion Coalition, cadmium is typically produced in places where zinc is refined rather than mined. Top producers of cadmium include China, Japan, Korea, Mexico
According to what the Minerals Edu ion Coalition believes, cadmium gets used in emergency power generation and electricity supply. It also finds its appli ion in nuclear rods to maintain the nuclear reactions within a limit as it can absorb neutrons.
Calcium minerals are very common and can be mined anywhere. It is chiefly obtained from limestone, dolomite and gypsum. Common calcium-bearing minerals include anhydrite calcium sulfate , gypsum hydrated calcium
