Dolomite powder
Used as Fillers by detergents, steel, paints and ceramics
Dolomite rock contains either Calcite or a mixture of Calcite & Magnesite in addition to dolomite are called "Dolomitic Limestone". It is grouped under flux & construction minerals and is important for iron & steel and ferro-alloys industries.It has high natural whiteness and its noted for their ease of dispersion. Its use improves properties such as wheather ability, reduces shrinkage, fissure development and water absorption.

Why our product
Rubber Products :
A huge market for dolomite is Rubber Industry manufacturing different products as Footwears, containers, etc.
Construction :
In a crushed manner it is used extensively in construction industry such as base of roads, aggregate in cement and filling in different manners. Railroad Ballast also invites huge usage of dolomite sand.
As a strainer :
Used in hydro power plants to strain all the impurities from water when used as sand formation.
Thermal Power Plants :
Due to its high resistance to heat it is used in kilns for lining in the inside part and also exterior.
Ceramic Industry :
Due to its hardness and high gravity it is used hugely in tiles and other ceramic based industries, as well as a sintering agent in iron ore pelletization and as a flux agent in steel making.
Chemical Industry :
Due to use of MgO in pharma and other scientific purposes, Dolomite is used in this industry also. Extraction of MgO from powder or chips is done through chemical process by treating it with various acids.
