  • Barite: The mineral Barite information and pictures

    Barite is the main ore of the element barium. It is also important in the manufacture of paper and rubber. Barite is also used in radiology for x-rays of the digestive system. When crushed, it is added to mud to form barium mud, which is poured into oil wells during drilling. A rich, white pigment was once made from crushed Barite.
