Dolomite is a mineral that is usually found in dolostone deposits, which are sedimentary rocks. Its applications are driven by the intrinsic distinctions between dolomite and calcite It is a versatile mineral that is used across several industries such as construction, agriculture, ceramics, pharmaceuticals, paints, plastics, rubber and refractories to mention a few. The physical properties of dolomite are its soft to medium hardness with a value of 3 and 4 on the Mohs scale and the pearly luster. Dolomite is used as a source of magnesium in ceramic, glass, cement and pharmaceutical sectors. In the Iron and steel industries, dolomite is massively used because of its strength and compatibility in purifying iron and steel. For construction and building materials, it is used as a substitute for lime. Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), is an inorganic compound with formula Na5P3O10. The burnt dolomite is used in refractories, as a sintering agent in the palletization of iron ore and as a flux agent in the production of steel. Paints, plastics, rubber, soaps, and detergents sectors use it as filler in their manufacturing processes. Farmers use dolomite to adjust the pH of their crops. It is also used in the chemical industry to make magnesium salts such as magnesia and magnesium oxide (MgO), which is further utilised in pharmaceuticals. The distinguishing characteristics of our natural dolomite are: High purity grade along with whiteness. Our Dolomite has high compressive and shear strength. It also has the wet ability and fire-resistant. The strength of our mineral dolomite is its long life and rigidity. The structure of dolomite is like that of calcite, except every other cation layer contains magnesium ions instead of calcium ions. But, if we compare dolomite to calcite, its usage will be less prevalent within the industries. This is because of the lack of brightness in the dolomite mineral. We provide cutting-edge and high grade dolomite minerals that can be used in a variety of applications. In order to meet all diverse demands, we can add additional refining operations to our standard dolomite mineral production to suit the bespoke requirements of various sectors and industries.

Soda Feldspar is generally a clean white mineral which sources sodium, alumina, and silica along with some potassium and calcium. Albite mineral from which soda feldspar is derived is often tends to be white in appearance compared with the pinkish hue of orthoclase mineral from which potash feldspar is ground. Feldspar is used as a flux in ceramic and glass industries. It also adds strength to the body. Feldspar is a rare occurrence of extremely pure mineral free from mica. The chief use of Feldspar is in the Ceramic and Glass Industries. In ceramic bodies, the main vitrifying (fluxing) agent is feldspar. Application Industries: Ceramics, Tiles and Sanitaryware Glazes Glass Industry Bonding agent for abrasives, wheels, discs, and other shapes. Dental ceramics. Product Variants: Granular Particles Powder form (100-350 Mess BSS) Lumps (Dressed ore in raw form) Packing: The standard packing units are 50 kg HDPE Bags, 1000 Kg, and 1350 Kg jumbo bags. However, we can also make the packing units as per customer requirements.

Our Bentonite Products: Foundry Grade: The foundry-grade bentonite powder is used as a bonding material in the preparation of moulding sand for the production of iron, steel, and non-ferrous casting. Sodium Bentonite is the preferred binding agent for use in the bonding of metals and foundry sands, although calcium Bentonite enhances foundry sandâ??s flow ability and figures in the manufacture of nonferrous mouldings. Drilling Grade (API Grades, OCMA) Drilling-grade bentonite is a naturally occurring clay containing the clay minerals of smectite. It can also contain accessory minerals, such as quartz, mica, feldspar, and calcite. The Drilling Grade Bentonite Powder is used as a mud constituent for oil and water well drilling. Its roles are mainly to seal the borehole walls, remove drill cuttings, and lubricate the cutting head. Our Drilling Grade Bentonite Powder has high swelling and good colloidal nature, which can increase the viscosity of suspension in the drilling mud and also can increase the lubrication of drilling, as well as for the rig-freeing agent. Piling Grade Bentonite slurry is one of the most common excavation fluid used in constructing diaphragm walls. The gel strength and viscosity properties of the bentonite clay allow for cutting suspension and removal. Piling Grade Bentonite Powder is used traditionally as a support and lubricant agent in walls and foundations, tunnelling, and horizontal drilling. Viscosity and plasticity play a very important role. Bentonite slurry walls are used in construction, where the slurry wall is a trench filled with a thick colloidal mixture of Bentonite and water. Cattle Feed Grade Our Feed Grade Bentonite is Natural & selected from affluent Mines of Kutch. This Bentonite is used as an animal feed supplement, as a palletizing aid in the production of feed pallets, as well as a flow ability aid. It slows the passage of feed through the digestive system increasing the uptake of nutrients. Bentonite has an affinity for some of the active elements of toxin products formed by bacteria in the digestive tract, and its application in feed allows more rapid weight gain of livestock.
