Jun 21, 2019· In the quartz sand extraction process, because there are fewer impurities in the raw ore, the main beneficiation process is to purify and remove a small amount of impurities in quartz sand. Currently, the processes used include: classification and desliming, scrubbing, magnetic separation, flotation, acid leaching and so on.
