PROCESS OF SILICA PARIS (QUARTZ SAND)PASIR KWARSA BANGKA, PASIR KWARSA LAMPUNGQuartz sand is a quarry consisting of silica crystals (SiO2) and contains impurities which are carried during the deposition process. Quartz sand also known as white sand is the result of weathering of rocks containing major minerals, such as quartz and feldspar. Weathering results are then washed and carried by water or wind deposited on the banks of rivers, lakes or the sea.Quartz sand, mainly used in glass, optical, ceramic and abrasive industries. Non-cement quartz sand is used as a base or additional material for the construction of toll roads and airports, also for the manufacture of highways, building materials and asphalt. The largest quartz sand reserves are in West Sumatra, other potentials are in West Kalimantan, West Java, South Sumatra, South Kalimantan, and Bangka and Belitung Islands. Quartz sand is a quarry consisting of silica crystals (SiO2) and contains impurities which are carried during the deposition process.Quartz sand also known as white sand is the result of weathering of rocks containing major minerals, such as quartz and feldspar. Weathering results are then washed and carried by water or wind deposited on the banks of rivers, lakes or the sea. Quartz sand in Indonesia is better known as white sand because it consists of white ones. Quartz sand is a placer / alluvial deposit that occurs from the weathering of rocks that contain many quartz minerals (SiO2) and then experience natural transportation, carried by transport media (water / ice) which are then deposited and accumulated in basins (lake , beach and others). Quartz crystals are native to nature because of their hardness, resistant to acids and bases.As a precipitate, put (placer) quartz sand can be materials released as sand, and can also continue to undergo a subsequent process is consolidated into sandstones with high silica content, for example protokuarsite (75-95% quartz) and orthokuarsite ( > 95% quartz).The quartz sand put in Banten is loose quartz sand which is generally associated with alluvial deposits. This type of quartz sand is due to the breakdown of origin rocks such as granite, granodiorite and dacite, or older quartz sandstones.Physical and Chemical PropertiesQuartz Sand GranulesViolence: 7.0Specific gravity: 2.60 - 2.66White, clear or other colors depend on the polluting compounds; for example, the yellow color contains Fe-oxide, the red color contains Cu-oxideScratches: WhiteGloss: Vitrious / glassHemisphere: NoneFraction: ConchoidalMelting point: 1715?

Non-cement quartz sand is used as a base or additional material for the construction of toll roads and airports, as well as for the manufacture of highways, building materials and asphalt.Standard sand to test portland cement and fly must be used for natural quartz sand. Caterpillar, clean, hard, and meet the conditions below:Silica content (SiO2); minimum 95.0%?? Silica content (SiO2); the maximum dissolved in HCI is 0.25%?? Organic content levels, compared with standard colors: clearer than standard colors?? Mud content: 0.0%?? The grain composition, between holes 1.2 and 0.6 mm, is 100? 2%The role of quartz sand in iron casting activities is very important. In general, castings are made of sand with clay or bentonite binders. Quartz sand must be able to form with strength, chemical composition and large size distribution of suitable grain. This situation is very important to avoid cast defects. Besides that quartz sand is also important for the chemical industry, paint industry, abrasives, refractories, mineral fillers, ceramic industries (glass, glass sheets and so on).
