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.
