Unimin company of the United States occupies the ''high grade'' high-purity quartz (lower 30 ppm) pro-duced in the world, and the origin is the ...

1. Washing-classifying-desilting: In the quartz sand beneficiation process, the fine-grained grade with a particle size of less than 0.1 mm is usually called slime.For quartz sand with a large amount of clay and ore mud, as the particle size becomes finer, the grade of silica gradually decreases, while impurities such as iron and aluminum rise instead.
