Washing and classifying desliming . The SiO 2 grade in quartz sand decreases by quartz sand size becoming finer, so washing and desliming of crude quartz sand is necessary before next step.. Scrubbing . Scrubbing is the way to remove film iron and impurity minerals on the surface of quartz by mechanical force and crush these mineral aggregate.

Leaching also leaves behind manganese, quartz, aluminum and hydroxides of iron, forming a type of soil called laterite. When the residual materials accumulate and are redeposited in the lower layer of the soil, they may coalesce and form tough and impermeable layers called duricrusts.
