Cobaltite

CoAsS - Mohs Hardness: 5 1/2.   Cobaltite is a sulfide mineral. It contains up to 10 percent iron and variable amounts of nickel. Although rare, it is mined as a significant source of the strategically important metal cobalt. Cobalt is primarily used in the preparation wear-resistant and high strength alloys. The compounds, cobalt silicate and cobalt (II) aluminate (CoAl2O4) give a distinctive deep blue color to glass and paints. Lithium cobalt oxide (LiCoO2) is widely used in lithium ion battery cathodes.
