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.

Dolomite is a carbonate mineral, including ankerite and manganese dolomite. Its crystal structure is like calcite and is often rhombohedral. It will bubble slowly when exposed to cold dilute hydrochloric acid. Some dolomite emits orange light under cathode ray irradiation. Dolomite is the main mineral composition of dolomite and dolomitic limestone. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy conservation and other fields. It is mainly used as flux for basic refractory and blast furnace ironmaking. Production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; As well as ingredients for producing glass and ceramics.
