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. Barite is also a very popular and common mineral among ...
