· Barite (barium sulfate, BaSO 4) contains 58.8 % barium and has a specific gravity of (4.2–4.5). The barite used in drilling fluid, which is normally impure, is of lower specific gravity as it contains other minerals such as quartz, chert, calcite, anhydrite, celestite, and various silicates. Also, it consists of other iron minerals, some of ...

· The specific gravity of the barite is large, generally 4-4.6, and it also has a good floatability. The barite flotation process is mainly used to separate the sedimentary barite and hydrothermal barite ore associated with sulfide ore and fluorite based on the difference of surface physical and chemical properties between barite and associated ...

Barytes (or barite) is a naturally occurring mineral form of barium sulphate. It is extracted by both surface and underground mining. Its main properties are its high specific gravity 4.2 – 4.5, very low solubility; it is non-toxic, and also chemically and physically non-reactive, low abrasiveness and opaqueness to x-rays.

· The density of any material is derived by multiplying the specific gravity of that material by the density of pure water. For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal. Conversely, to convert from density to specific gravity, divide the density of a material or mud by the density of pure water.

Barite is a mineral composed of barium sulfate (BaSO4). 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 ...

· Barite has high density and low hardness, so gravity separation is the preferred beneficiation method. If gravity beneficiation is used only, the barite recovery rate is low due to complex barite mineral group. So it is appropriate to adopt flotation, the combined process of gravity separation plus flotation, magnetic separation, etc.
