Application

Use as materials of oil-drilling mud fluid as weighting additives to increase the mud weight without increasing the solid content. And, it as filling/padding & carrier materials mainly used for water-based paints, printing inks, plastics, rubber, paper, pharmaceuticals, ceramics, cosmetics, etc. The mineral has high specific gravity to be use for increasing mud density in many types of drilling fluid systems, etc.
