The quartz sand can also be processed into quartz powder through drying and grinding. Technical process of silica sand processing and washing plant The following is the usual purification process of quartz sand. The raw ore is crushed and screened to remove impurities, then washed and scrubbed to further remove the impurities from quartz sand.
The dissolved quartz sand is then recovered using a process similar to the hydrofluoric acid method. This method is less toxic but may require more time and energy to complete.
