Barite is a mineral composed of barium sulfate (BaSO 4 ). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and ...

over direct flotation as a dynamic multiphasic and high efficiency selective process of quartz beneficiation. Reverse flotation process is used to separate minerals im-purities as concentrate from valuable mineral as tailings. In our case, impurities are presented by mica, dolomite, barite, hematite, iron oxides and feldspar.
