Scrubbing: The scrubbing process mainly removes the iron film and other adherent impurities on the surface of quartz sand through the friction between mechanical force and quartz particles, and further crushes the quartz particles. Subsequently, the fine-grained particles are separated from the scrubbing slurry by a hydrocyclone to obtain higher-purity quartz sand.
