Silicon is the second most common element in the Earth's crust, comprising 25.7% of the Earth crust by weight. It is shiny, dark gray with a tint of blue. Silicon is never found in its natural state, but rather in combination with oxygen as a silicate ion (SiO4) in silica-rich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals. Silicon alloys with a variety of metals, including iron, aluminum, copper, nickel, manganese and ferrochromium.
Silica which is the chemical name of quartz and a synonym for silicon dioxide is widely used in manufacture of special steels and cast iron, aluminum alloys, glass and refractory materials, ceramics, abrasives, water filtration, component of hydraulic cements, rubber reinforcing agent, etc
Rounded pebbles of chalcedony are used in ball mills for finer crushing of minerals like felspar, calcite, and barytes. Chalcedony being the cryptocrystalline variety of silica is very hard and has good abrasive effect on the material to be pulverized. Some of the ball mills use steel shots for this purpose. Chalcedony pebbles are used to advantage where product absolutely free from iron contamination is required. The agate pieces after cutting to requisite sizes and shapes are utilized in the manufacture of fulcra of scientific balances and making edges, planes and bearing of precision instruments.
Cambay and Varanasi are important agate cutting centres. Big pebbles are used for making mortar and pestle. Glass-sand in large quantities is used as moulding sand in the foundry industry, as body constituent in the ceramic industry in the preparation of glazes and sometimes added to the raw material for cement manufacture to balance SiO2, Al2O3 and Fe2O3 percentages. Silica flour made by grinding silica sand is used in paints. Paint manufacturers generally prefer diatomite powder which has a wide covering powder.
In silica quarry, it’s important to choose right crushing equipment and grinding equipment for silica pulverization. Usually this is the essential procedure before the silica being processed in the dressing.
