Quartz

It is used for: special lenses and prisms and quartz-glass tubes for unlamps laboratory tubes and crucibles glass.

Mica

The platelet particle shape of Mica offers excellent flexural modulus properties, improved heat resistance, electrical properties and mechanical properties.

Talc

Talc, the softest of all minerals is known to everyone because of talcum powder. The softness, flakiness, and stability of talc makes it a desirable substance for many purpose.

Feldspar

In making the body composition of several types of procelain, china and earthenware and also in the preparation of glazes and enamel.

Calcite

Uses: In cements and mortars, production of lime, limestone is used in the steel industry.


Feldspar

mica

Feldspar is generally used for three purposes :


In making the body composition of several types of procelain, china and earthenware and also in the preparation of glazes and enamel.


As an important ingredient in the glass sand batch. As a bonding agent in the manufacture of bonded abrasives like wheels and discs of garnet, corundum, emery etc.

The glass and ceramic industries are the major consumers of feldspar and account for 95% of the total consumption. In ceramic bodies, the main vitrifying (fluxing) agent is feldspar. The majority of white ware bodies contain good proportions of feldspar. It acts as a flux. In the ceramic industry, the flux is defined as that portion of the body which develops glass phase. This is provided mostly by feldspar.
