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.

Quite a few people have been asking about washing meth, so here's one of the easiest (IMHO) ways to go about it. You can get everything over-the-counter… except the meth You can also do it using a coffee filter, but I've found that yields suffer due to meth getting caught in the filter. Acetone will remove MOST impurities, but some will get through.
