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.
The concentration of silica in the scrubbing brine was 530 mg/kg in the experiments so that it was silica under-saturated. If scrubbing of superheated steam occurs at a high brine–steam ratio, the silica concentration in the brine will be slightly less and the brine will under-saturated with silica at the scrubbing temperature.
Silica scrubber is used to wash the slurry with a concentration of 68~70%, wash the mud and clay on the ore or sand. It create conditions for the beneficiation operation, and also apply to other crucibles. Washing industry. Used for the dispersion of slime, removal and scrubbing of mineral surface impurities.
Scrubbing is a better choice than flotation for removing silica from the coarse fractions. The P 2 O 5 grade of the coarse fractions is increased to about 30% by scrubbing and the product yields are higher than those obtained by flotation. The silica in the fine fraction is separated by reverse flotation.
For this purpose, a mixture of hydrochloric and oxalic acids was used and the effects of variable parameters such as leaching temperature, leaching time, acid concentration …
