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.)
Barite is a mineral composed of barium sulfate, BaSO4. It is usually colorless or milky white, but can be almost any color, depending on the impurities trapped in the crystals during their formation. Barite is relatively soft, measuring 3-3.5 on Mohs' scale of hardness. It is unusually heavy for a non-metallic mineral. The high density is responsible for its value in many applications. Barite is chemically inert and insoluble.
Barite (BaSO4) is a nonmetallic mineral used primarily as a weighting agent in drilling muds in the oil and gas industry, due to its relatively high specific gravity (4.2). The bulk of Pands ’s barite was used for oil-field drilling fluids. Barite can also be used for the manufacture of lithopone (a white paint pigment) and as a filler in paint, paper, rubber, linoleum, and cloth. Barite deposits of Pands Group are present in Loei,Cheing Mai,Kanchanaburi,Nakhon si thammarat and Laos.
By far, the principal use for barite is as a “weighting agent” in oil and natural gas drilling. In this process, barite is crushed and mixed with water and other materials. It is then pumped into the drill hole. The weight of this mixture counteracts the force of the oil and gas when it is released from the ground. This allows the oil and gas rig operators to prevent the explosive release of the oil and gas from the ground. Currently, the majority of barite consumption in Thailand is for this drilling application. However, the consumption in drilling "mud" fluctuates from year to year, as it is dependent on the amount of exploration drilling for oil and gas, which in turn depends on oil and gas prices.
Beyond this, barite is used as an additive to paints, enamels, and plastics, in the production of so-called "lead" crystal or "leaded" glass, stops radiation from computer monitors and television tubes, and as the source of barium chemicals.
Barite has the unique ability to strongly absorb X-rays and gamma rays. Consequently, it is used in medical science for special X-ray tests on the intestines and colon. It is also mixed with cement to make special containers used to store radioactive materials. A more recent application of barite is in the production of brake pads and clutches for cars and truck
A dense mineral comprising barium sulfate (BaSO4). Commonly 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, where API specifies grinding to a particle size of 3 to74 microns. 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
Mining and Productions
Pands Group is the country’s biggest holder of mineral mine concession certificate, under the name of P&S Barite Mining Co., Ltd. of which affiliates are all over the country, as well as in Laos. The company’s scope of work is the barite mining and ore grinding of which products can be used in other industries, such as brake pads, paint products, natural gas and oil drilling etc. The company is certified with API, TIS, and ISO 14001-2004 | 9001-2000. Our mines can be categorized in two types: open pit mine and underground mine. Our products will be available for each client’s order and for exportation.
