Barite
Barite is the principal ore of barium. Barium has very high number of applications. It is known to have more than 2000 industrial uses. However, the majority of barite mined is not used to extract barium. It is valuable in its native form because of high density. It is mostly used by oil & gas industry as an ingredient of drilling mud.
