QUARTZ AND FELDSPAR MANUFACTURING

(A)QUARTZ
Quartz is a mineral, which is a member of silica groups. It is present in silica rich-igneous rocks and it is the basic materials of sandstone and is found in metamorphic rock lime gneisses, schists, charnockites and khondalites If pure, quartz is a colorless, transparent, and very hard crystalline material of glass-like look. The well-known rock crystals – six-sided prisms with a six-sided pyramid at their ends – are simply well formed crystals of quartz.

Quartz appears in a number of colored varieties, like amethyst (violet), citrine (yellow), or smoky quartz (gray, brown to black). It also occurs in dense forms with no visible crystals, like the multi-colored agate and the gray flint.

The term ‘quartz’ is often referred to as a synonym for silica. Silica (SiO2) is one of the ubiquitous materials in the earth’s crust. Quartz, quartz crystals, quartzite, silica sand, sand (others) and moulding sand are all coined together in one generic name ‘silica minerals’. This is because all these commodities are essentially crystalline silicon dioxide (SiO2) with variations mostly related to their crystalline structure and presence of minor or trace impurities. Silica occurs in several forms giving rise to different varieties.

Crystalline Varieties

The important varieties of crystalline quartz are vein quartz (massive crystalline quartz); milky quartz (white, translucent to opaque); ferruginous quartz (containing brown limonite and red haematite and almost opaque); aventurine quartz (containing glistening flakes of mica or haematite); cat’s eye (opalescent greenish quartz with fibrous structure); rock crystal (clear, colourless, well-crystallised transparent quartz); amethyst (clear-purple or violet-blue), transparent quartz; rose quartz; smoky quartz; etc. Occurrences of massive crystalline quartz in veins or pegmatites have been recorded in almost all the states.
Clastic or Granular Varieties
These varieties include sand consisting largely of unconsolidated quartzose grains (0.06 mm to 2 mm diameter), gravel consisting largely of unconsolidated coarse quartzose grains or pebbles (2 mm to 8 mm in diameter), sandstone and quartzite. The occurrences are reported from Andhra Pradesh, Bihar, Delhi, Haryana, Karnataka, Kerala, Madhya Pradesh, Rajasthan, Tamil Nadu, Uttar Pradesh, etc. The silica sand from Naini area in Allahabad district, Uttar Pradesh is of a very high quality.
Cryptocrystalline Varieties
This group includes chalcedony, agate, jasper, onyx, flint and chert. These varieties appear noncrystalline (amorphous) in hand specimens, but under microscope show double refraction which reveals their concealed crystalline nature. These varieties are reported from Gujarat, Uttar Pradesh, Tamil Nadu, Andhra Pradesh, Maharashtra, Madhya Pradesh, Karnataka and Punjab. The most important occurrences of agate are in Ratnapur, Rajpipla area and further west between Tapi and Narmada rivers in Bharuch district, Gujarat, where it is found as pebbles in varying sizes associated with clay washed down by the river flow. Other occurrences of economic importance are reported from Amravati, Aurangabad, Buldhana, Chandrapur, Nashik and Pune districts in Maharashtra; beds of Krishna and Godavari rivers in Andhra Pradesh; Dumka district in Jharkhand; Dhar, Mandsaur, Sihore and Shahdol districts in Madhya Pradesh; and Kachchh district in Gujarat.
