Bentonite as is a particular kind of clay derived from volcanic ash and consists mainly of montmorillonite with minor amount of illite, kaolinite, cristobalite and other minerals. Bentonite has strong colloidal properties and, when in contact with water, increases its volume several fold by swelling, forming a tixotropic, gelatinous substance. Main uses of Bentonite take advantage of these colloidal properties. The main characteristics of Bentonite is its decolorizing power, that is the property of the earth to absorb selectively certain pigments rather than others according to the characteristics of the product to be decolourized(acidity, oxidation degree, origin and biological state etc.) APPLICATIONS For Drilling Fluids Pilling Binder (e.g. foundry-sand bond, iron ore pelletizer) Purifier Electrical Earthing Agriculture Cosmetics, Paper, Paints and Ceramics Absorbent (e.g. pet litter), and As a Groundwater Barrier. We CEMENTATION acquire own mines for Bentonite in India. We supply Bentonite for industrial, manufacturing, construction and drilling applications. Our production or supply capacity is more than 250,000 TPA. At CEMENTATION a special attention is given while mining Bentonite as the materials physical and chemical properties are depended upon the interference of the other metal ions present in the soil. Once the material sourced from mines are transferred to our factory and are left for drying in an open land to reduce moisture up to the desired level. After the drying process and other checks are done our skilled manpower will do a sorting of the material and then after the material goes to pulverizes for grinding to desired mesh size and are packed according to customers requirement. Our laboratories are well equipped to meet the needs of the diverse markets we serve.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Our monthly ability to export Iron Ore is of 2000-5000MT per month.
