Quartz is the name given to very pure silicon dioxide crystals. Quartz grains with a specific gravity of 2.65 g / cm³ and hardness of 7 are very common. The quartz crystallized in the hexagonal system can be found in crystalline or amorphous state in nature.The formula for Quartz is SiO2, and in pure form % Si 46.5% and 53.3 contains O2. The Mohs scale hardness 7 specific gravity 2.65 g / cm3, melting temperature of 1785 °C and is one of the fairly common minerals in the Earth's crust. The main elements in solid solution in natural quartz
The world's largest quartz deposits in Brazil are located. Known, of course, ultra-pure quartz reserves in Brazil, USA, Namibia, Angola, Madagascar, China, and India are located in. Either the primary or secondary formations, and these reserves do not show continuity. Such quartz is well qualified to be used in electronic industries. Also in Brazil, the world's best and largest amethysts are available. Amorphous or cryptocrystalline Quartz ore, Argentina, Austria, Belgium, Luxembourg, Hungary, South Africa, Spain and Norway are located. Quartz related to to reliable sources of World reserves could not be reached. Pure quartz is used as an ornamental stone and crystals, optical and electronic industries.
In the chemical industry, the metal is consumed in the production of crystalline silicon and the Crucible. Ultra-pure quartz optical, electronic and electrical industries. Besides grinding quartz, glass, detergent, paint, ceramic, sand, fill, and metallurgical industries consumed. Quartz is generally produced by open pit method. After detonated using a an explosive device is almost negligible, which cover over quartz is subjected to triage. Clean and high quality ones are gathered by hand. Grinding mineral processing methods with the tenor at the end of Fe2O3 is reduced. Quartz is sometimes broken and extracted, washed with water to make it cleaner. Quartz crystals are used in optical and electronic industries % 99.99% SiO2 are required to contain.
Quartz, usually in Turkey the fault zones, cracks, as a gangue mineral in ore deposits and is found in silos. Research and studies for the determination of quartz reserves of Turkey are insufficient. Quartz glass, ceramics, detergents, fillers, filter industry is an important entry. Manual collection of the production is in the form of quartz crystals, while the quartz of the fleet is carried out with the method of operating the open pit production. Broken quartz, are washed with water if necessary. Requested the quality and the size is brought by applying the methods of grinding and mineral processing.
Quartz sand, Quartz We rich igneous, and metamorphic rocks as a result of the weathering of less than 2 mm Quartz (SiO2) particles. The sand is white quartz
The main usage of quartz sand, glass and foundry industries and areas in the construction industry, abrasives production, metallurgy, detergent, paint, plastic, rubber, ceramic industry and oil production are used. Click 250.510.000.000 of quartz sand HS is. Quartz sand reserve of billion tons of Earth in a healthy way can not be calculated, although it is known that at a level. Quartz sand reserves
To constitute the raw material for glass production quartz sand with a minimum of 98% SiO2, a maximum of 0.1% Fe2O3, and contain 0.106 to 0.5 mm grain size range should be.
Fire resistance of quartz sand used in the manufacture of silica brick, a minimum of 1700 °C should be. Also the ratio of SiO2 % 95-99, the rate of Fe2O3 0.3% -1.3, AI2O3 content % 0.1-2.8, the CAO content % 0.2-2.4, na2o and K2O, the content of which is 0.2% to 1.5 should be. Low quality of silica brick production 87% -96% SiO2 containing quartz sand is made from.
Quartz sand SiO2 ratio of dross to be used as the minimum 90%, AI2O3, and Fe2O3 in the ratio of maximum 1.5%, maximum MgO and Cao content of 0.2% should be.
Silicon and ferro silicon to be used in the production of quartz sand SiO2 ratio is minimum % 96-98, AI2O3, and Fe2O3 ratio is a maximum of 0.2% should be.
In the production of aerated concrete (ytong type) quartz and quartzite sand ratio of SiO2 to be used at least % 75.5 construction sand, at least 95% of brick-making, at the very least, must be collected.
Quartz sand is used in pottery clay that the SiO2 content of 90% -92, AI2O3 content of 6-8%, Fe2O3 content of 0.5%, the rate of TiO2 must be 0.45.
