Quartzite Minerals

Name and composition - Metamorphic siliceous rock consists of quartz (SiO2) grains cemented by siliceous matter.

Physical Properties - Hard and compact, fine grained, whitish, ceramic, greyish coloured, bedded to massive rocks.

Mode of Occurrence - Quartzite is a meta sedimentary rock which generally occurs in bedded form.

Uses - Quartzite is used as refractory, dimensional & flux material.

Mineral based Industries – Copper smelter uses quartzite as flux.

Industrial Prospects – Glass & ceramic industry.
