40 Common Minerals and Their Uses

Ore is essential to iron and steel production. Also used in the making of manganese ferroalloys. Construction, machinery and transportation end uses account for most U.S. consumption of manganese. Manganese ore has not been produced in the U.S. since 1970. Major producers are South Africa, Australia, China, Gabon and Brazil. The U.S.


Since talc is generally fairly to very hydrophobic, the very fine talc slimes can adhere to air bubbles to such a degree that talc ''crowds out'' the PGM-containing minerals on the bubbles and therefore reduces PGM recovery. Typically CMC is used to depress the talc. Further, use of low frothing reagents is beneficial to minimize talc flotation.

Talc | Imerys

Talc is a hydrated magnesium silicate. There are many types of talc and each ore body has its own features, its own geology, formed many millions of years ago. As a natural ore, talc is always found in combination with at least one other mineral. The most common of these is chlorite, a chemically and structurally similar ore.
