Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for high-pressure zones experienced during drilling, thus suppressing high formation pressures and preventing blowouts.

The increase in fluid density is attributed to the high density of Micromax additive (4.8 g/cm 3) compared to that of barite (4.2–4.4 g/cm 3); therefore, less solid content will be required to provide the same density (Caenn et al. 2011; Al-Muhailan et al. 2014; Mustapai 2011). Conversely, increasing the concentration of Micromax additive up ...

adopted [6–8]. Usually, when the specific gravity between the barite and gangue has a hinder-settling ratio between 1.5 and 2.5 [19], gravity concentration (jigging, tabling and spiral concentration) is used for coarsely liberated ores (-2000 ? 150 lm) particles [4, 9, 11, 19, 20]. Magnetic separation can be used to remove iron oxides gangue ...

Barite (spelled baryte in British publications) was named from the Greek word baros which means weighty, a reference to its unusually high specific gravity. (Specific gravity is a mineralogist's measure of the density of a mineral; this is done by comparing the weight of the mineral to the weight of an equal volume of water.) Sources

each ground low grade barite particle such that the discrete particles have a specific gravity of 4.10, or 2) that the quartz (and other low gravity contaminants) exists as separate particles with a specific gravity of +/- 2.6 and that pure barite particles exist as separate particles with a specific gravity of 4.5.

Due to its low cost and high selectivity in the concentration process, gravity methods such as jigs for coarse barite ores and shaking tables for the concentration of fine barite ores are generally used. However, the very fine barite minerals (under 75 m) can not be concentrated efficiently using these gravity methods.

It is a dense non-metallic mineral with an average SG

 — By adding barite powder to the mud, the density of the fluid increases, which helps prevent blowouts and controls well pressure. Additionally, barite helps to cool and lubricate the drilling bit and remove rock chips from the borehole. Paints and Coatings. In the world of paints and coatings, barite powder plays a crucial role as a filler.

 — Determination of specific gravity. Barite samples of 15.36 g and 15.38 g respectively were obtained by riffling due to the size of the density bottle. The samples were then oven-dried at 105 °C and placed in an airtight container. The density bottle was washed, dried, and its weight was determined as M 1.

The name Barite comes from the Greek word "Barys" or "Heavy" because barite has a high-specific gravity of around 4.5, making it surprisingly heavy for a non-metallic mineral. ...
