The as-received silica sand was subjected to attrition scrubbing experiments. Attrition was conducted to remove clay minerals and dust covering silica grains which could increase reagent consumption. Attrition experiments were carried out in a 2-L glass beaker where a 250-g sand sample was added to 1000 mL distilled water (20% solids).

Silica sand for glass making needs a low content of iron. It is known that there is an iron-rich coating on the particle surface and in fissures, which makes silica sand high in iron content and rusty in appearance. Iron coating sticks on the surface so firmly that the common mechanical scrubbing method is not effective.
