Barite is extensively used as drilling mud in oil exploration operations. Beneficiation of barite by flotation was investigated using cationic and anionic collectors. Commercially available fatty amines such as Armoflote 17 and Liquid B50 were tried as collectors to float gangue minerals (reverse flotation) whereas oleic acid was used for direct flotation of barite.
The final, eighth chapter of the report describes the current trends in the development of the barite products market and provides a forecast for barite consumption in …
Barite beneficiation belongs to non-metallic beneficiation and is a sulfate mineral. Its crystals are often thick plates, and the aggregates are granular or crystal clusters. Barite is insoluble in water and acid, non-toxic, non-magnetic, and can absorb X-rays and Y-rays. It is mainly used in petroleum, chemical, paint, filler and other ...

Barite (or baryte) is an important industrial mineral of composition BaSO4. Barite used extensively in the oil industry as a weighting agent for drilling muds. For many uses barites must meet strict criteria for example specific gravity (relative density), and trace element composition. Barite is a mineral that comprises barium sulfate (BaSO4).
