Barite, barites, or heavy spar, a white, yellow, blue, red, or colorless mineral. It is a sulfate of barium, BaSO4, found in nature as tabular crystals or in granular or massive form and has a high specific gravity. The mineral is widely distributed throughout the world. It often occurs in veins with lead and zinc minerals. It is insoluble in water, and this property is made use of in testing for the sulfate radical.Barite Uses
Drilling
Weighting material with a specific gravity of 4.37 used to increase the apparent density of a liquid drilling fluid system. Barite [BaSO4] is the most common weighting agent used today. It is a mined material ground to an API specification such that particle sizes are predominantly in the 3 to 74 micron range.
Drilling Fluids
A dense mineral comprising barium sulfate [BaSO4] that commonly occurs with a range of accessory minerals, such as quartz, chert, dolomite, calcite, siderite and metal sulfides. Used as a weighting agent for all types of drilling fluids, barites are mined in many areas worldwide and shipped as ore to grinding plants in strategic locations. Pure barium sulfate has a specific gravity of 4.50 g/cm3, but drilling-grade barite is expected to have a specific gravity of at least 4.20 g/cm3 to meet API specifications. Contaminants in barite, such as cement, siderite, pyrrhotite, gypsum and anhydrite, can cause problems in certain mud systems and should be evaluated in any quality assurance program for drilling-mud additives.
Paint Industry
In dope and painting, it can be used as filling and can take the place of some expensive material such as basofor, crypton, titanium dioxide, activity, monox etc. Control the viscosity of the paint compatibly to make the products with bright color, good stability.
Plastic Industry
In plastic industry, it is used as the filling of plastic ABS to make the products with bright color. It also can improve the intensity, stiffness and abrasive resistance.
Pharmaceutical Industry
In medicine, it can be used as barium meal material for the intestines and stomach reflection, and also the filling for plaster and dope to extend the time limit.
Rubber Industry
In rubber industry, the products less than 500 mesh can be used as the filling of rubber products to save cost. It can improve the intensity, and acid, alkali, and water proof, and also has benefit for the Natural Rubber and Synthetic Rubber. More..
