Quartz is insoluble in acid (except hydrofluoric acid). By dissolving iron and other harmful elements with acid, impurities are separated and high purity quartz sand is obtained. Impurities in the surface and crevices of quartz sand can be removed by acid leaching to the maximum extent. Physical methods such as magnetic separation and flotation
