silica sand glass

Election process silica or silica sand concentrates from silica or silica sand ore carve . The industrial silica and impurities meet the requirements of quartzite, Quartz sandstone, quartzite veins referred to as silica. And the dominant component of quartz sand , river sand, sand etc lake called silica sand . Pure silica , silicon Theoretical chemical composition of the sand SiO2. Impurities associated with mineral mica , feldspar, iron-bearing minerals and clay . Silica and silica sand glass industry is The largest user , in addition to the metallurgical, chemical , building materials, electronics and other industrial sectors are also widely used. Metallurgical industry , smelting ferrosilicon used silica or silicon Sand into different grades according to the chemical composition ; refractory products in addition to its chemical constituents have asked outside of refractoriness , density ( represented by water absorption ) have to be Requirements. Beneficiation methods are commonly used to wash ore , grading, scrub , re-election , magnetic separation , flotation, chemical processing and so on. Ore beneficiation process should be based on the nature and Concentrate quality requirements. Chemical composition of pure silica ore using wet or dry grinding crushing a classification process to produce a quality standards Products . More ore or mineral impurities in the product quality requirements, you need to adopt a joint process includes several beneficiation methods, such as a scrub off the mud A magnetic separation ( or re-elect ) a flotation process . If ore is silica , ore should be crushing, screening, grinding , and then enter the sorting operation ; ore is dry When placer , sorting operation should be preceded by entering into a slurry with water to filter out coarse particles ; placer ore is wet , you can enter a coarse sieve after points Election operations.
