Mining Minerals

Quartz is the second most common mineral in the Earth's continental crust. It is made up of a lattice of silica (Si02) tetrahedral. Quartz has a hardness of 7 on the Mohs scale and a density of 2.65 g/cm3. The ideal crystal shape is a six-sided prism terminating with six sided pyramids at each end. Quartz is a common constituent of granite, sandstone, limestone, and many other igneous, sedimentary, and metamorphic rocks.

Talc is a soft hydrous magnesium silicate, also known as soapstone. The company has its own mines in village Karchha near about 65 kms from the factory . Different grades of talc ranging from 80% to 98% (whiteness) are excavated free from calcium and iron contents. DMGPL is producing high grade super snow white talc powder with latest machinery inbuilt with aerodynamic classification system to get uniform particle size on consistently.

PHYSICAL CHARACTERISTICS: -

It contains magnesium Oxide (Mgo) and silica (Sio2) mainly. Its Physical characteristics are as under:-

We can supply any whiteness in any mesh size up to 1500 mesh or 10 microns size.

China Clay is a Hydrated Aluminum Silicate,, which falls under the Kaolinite group of clays is formed by weathering or hydrothermal alteration of felspathic rocks. It has the general formula Al₂,(Si₂O₅)(OH)₄. Free Silica (grit) is the most undesirable impurity and is removed during processing by levigation, sedimentation or air-separation. First we collect the samples from various mines which is analysed for composition and physical and chemical properties and its suitability for various applications is then studied. Moreover, sustained availability of the material with no variation from mines is given utmost importance to ensure consistency in final product
