Cobalt
Cobalt is a silvery gray metal that has diverse uses due to its ferromagnetism, hardness and wear-resistance when alloyed with other metals, low thermal and electrical conductivity, high melting point, multiple valences, and color effects with silica. |

Cobalt—Styles of deposits and the search for primary deposits
Cobalt (Co) is a potentially critical mineral. The vast majority of cobalt is a byproduct of copper and (or) nickel production. Cobalt is increasingly used in magnets and rechargeable batteries. More than 50 percent of primary cobalt production is from th |
