For industrial purposes, two main classes of Bentonite exist: Sodium and Calcium Bentonite.
Sodium Bentonite used in drilling mud for oil and gas wells and for geotechnical and environmental investigations. Calcium Bentonite is used in oil bleaching purpose for Palm oil and it will not react with Soda and also don’t have swelling character.
Hematite, (Fe2 03)is the mineral form of iron oxide, one of several iron oxides ,colored black to steel or silver-gray, brown to reddish brown, or red. Hematite is used as a drilling fluid in oil drilling companies.
Industrial grade Guar Gum is used in Ceramics, Paints ,Textile Processing, Drilling Fluids, and many other industries. The purified grade is used in the Pharmaceuticals, Cosmetic and Food Industries.
Guar Gum when used in oil well drilling muds, gives a better colloid thereby reducing water losses. It regulates the viscosity of mud solution, stabilises and regulates the flow properties of the drilling muds.
Use of guar gum in the hydraulic fracturing (fracking) extraction of oil and shale gas as well.
Quartz is among the most common of all rock forming minerals and is found in many metamorphic rocks, sedimentary rocks, and those igneous rocks that are high in silica content such as granites and rhyolites. It is a common vein mineral and is often associated with mineral deposits.
Cryptocrystalline varieties are used as semi-precious stones and for ornamental purposes. These varieties are divided more by character than by colour. Chalcedony, or agate, is divided into innumerable types that have been named for locally common varieties.
