Frac Sand is a pure quartz sand which consist of very round sand grains. This sand is extremely durable and provides a crush-resistant material that can be employed in oil & gas industries for fracking also called as hydraulic fractioning. The rock units undergo multiple cycles of weathering and therefore are potential sources of frac sand.
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.
