The invention discloses a method for producing high-purity quartz sand. The method comprises the following steps: magnetic separation, floatation separation, staged de-sliming, acid-leaching washing, drying and finished product obtaining. Through magnetic separation, garnet, hematite, limonite, ilmenite and coenobium particles thereof are removed.
Silica sand washing process. Washed and graded. The grade of SiO2 in quartz sand decreases with the finer grain size of quartz sand, and the grade of impurity minerals is the opposite. This phenomenon is especially obvious in quartz sand containing a large number of clay minerals. Therefore, the quartz sand ore before the selection is carried out.
Silica sand washing plant for silica purification Quartz sand, also known as silica sand, can be made into high-purity quartz sand after beneficiation and purification, which is used in glass, ceramics, metallurgy, casting and refractory industries. After silica sand washed by a beneficiation plant, it can meets the industry standards.
Ordinary quartz sand, that is, SiO2 ≥ 90-99%, Fe2O3 ≤ 0.06-0.02%, fire resistance 1750 ℃. Ordinary quartz sand is generally a kind of water treatment filter material made of natural quartz ore, which is crushed, washed, dried and secondary screened;
