The Quartz sand to remove impurities from quartz sand are acid leaching and complexing. The acid leaching method uses the characteristics that quartz is insoluble in acid (except HF), and other impurity minerals can be dissolved by acid solution, and then further purification of quartz can be completed. The complex method is to use the quartz powder after acid leaching, the acid can form a coordination compound with the impurity ions in the solution, so that the impurity ions in the solution can be further removed.

Quartz sand is quartz particles made by crushing and processing quartz stone.

Quartz is a non-metallic mineral, a hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless and translucent, with a Mohs hardness of 7.

Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.

Quartz sand to remove impurities is a combination of various elements of oxidant, catalyst, penetrant, coupling agent, bleach, salt, edible acid and ETA. It has a coupling effect on oxides in minerals, and has no side effects on the ore body itself, human body and crops. Solvent cleaning uses the ability of the solvent to dissolve the contaminant. If the composition of the contaminant is known, it is useful to select a specific solvent.

Anyone who knows quartz sand knows that quartz sand has a wide range of uses and is a non-metallic mineral raw material. In the above, we also learned that the purification of quartz sand is difficult, mainly because it contains some other impurity minerals, among which the impurity minerals containing iron elements are: goethite, hematite, limonite, ilmenite, pyrite Iron ore, tourmaline, amphibole, biotite, etc. The presence of these impurities greatly reduces the use value of quartz sand, so iron removal from quartz sand is appropriately important.
