How to get high purity quartz sand？

High purity quartz sand (HPQS) is typically obtained from natural quartz deposits, but it can also be produced synthetically through chemical or physical processes.

One common method for obtaining HPQS is through a process called leaching. In this process, crushed quartz is mixed with a solution of hydrofluoric acid and an acid-stable emulsifier. The mixture is heated in a reaction vessel, and the resulting solution is filtered to remove impurities. The purified quartz solution is then precipitated using a neutralizing agent, washed, and dried to obtain HPQS.

Another method for obtaining HPQS is through a process called vapor deposition. In this process, a high-purity quartz rod is heated in a furnace, causing the quartz to vaporize. The vaporized quartz is then deposited onto a substrate, where it solidifies into a high-purity quartz film.

Other methods for obtaining HPQS include flotation, electrostatic separation, and magnetic separation.

Overall, the process used for obtaining HPQS will depend on factors such as the desired purity level, the quantity of material needed, and the available resources and equipment.
