It is based on the density difference between barite and gangue minerals. The specific gravity of barite is 4.2-4.6, while the particular gravity of gangue minerals such as quartz and calcite is 2.6-2.8. This large density difference makes gravity separation ideal for separating barite from other minerals. A jig separator usually separates The ...

The mineral barite (barium sulfate), also known as barytes, is most commonly found in hydrothermal veins and as veins in limestone. It is very dense (it has a high specific gravity) and is relatively soft. Those properties make it an excellent weighting agent in drilling muds for petroleum wells. In fact, worldwide, oil and gas drilling account ...

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 ...
