Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO3)2.  Dolomite is referred to as magnesian limestone. Its colour range varies between colourless to white, pale brown, greyish, reddish, or pink mineral. Dolomite is found in hydrothermal veins associated with lead, zinc, and copper ores.

Calcite is the principal constituent of  Limestone and Marble. These rocks are extremely common and make up a significant portion of Earth’s crust. They serve as one of the largest carbon repositories on our planet. Calcite, the most common form of natural calcium carbonate (CaCO3), is a widely distributed mineral known for the beautiful development and great variety of its crystals.

Properties that differentiate HTMC’s Dolomite and Calcite

Sourcing Strength

HTMC Sources it Lumps with the best whiteness, from Jhiri, Alwar and Udaipur. HTMC Has a strong presence in southern part of India with grinding locations up to 1,00,000 sq. feet, and with the dedicated infrastructure to produce 1,500 Mt per day.




Iron And Steel:

Dolomite grinded at HTMC finds a huge application in iron and steel industry due to its strength and compatibility in the process of purifying Iron and Steel.


Dolomite powder from HTMC finds usage in the detergent and soap industry owing to its whiteness and purity. Dolomite is less reactive and also exhibits good acid resistance which makes it a demanded mineral in various industries.


Calcite and dolomite produced at HTMC are used as a coagulant or stabilizer to prevent after precipitation of calcium carbonate from lime-softened water.


Calcite and dolomite developed by HTMC, are used as aggregate in Portland cement concrete for roads, buildings, and other structures and in combination with bituminous materials for roads and similar construction.


Calcite or dolomite from HTMC in the raw state, or when burned to lime, is an important constituent of the “batch” from which glass is made.


Calcite and Dolomite, grinded at ball mills, are applied to soils for correcting soil acidity, for adding calcium and magnesium, improving soil structure, maintaining or promoting favourable conditions for the utilization of soil nutrients by plants, and for the growth of desirable soil organisms.


Dolomite has been used as a source of calcium and magnesium for animal feeds since a long time. Calcite by HTMC is used in animal models, as a rich nutritional supplement.
