Silica Sand Mining introduces. Foundry silica sand is the quartz as the main mineral composition, particle size of 0.020 mm to 3.350 mm refractory particles, according to the mining and processing methods of different can be divided into artificial silica sand and sand washing, sand washing, selection of natural silica sand such as sand ...Generally, the mixed acid composed of the above acids is used for acid leaching and removal of impurity minerals. The degree of acid leaching should be based on the final quality requirements of silica sand. Try to reduce the acid concentration, temperature, and dosage to achieve silica purification at a lower beneficiation cost. 7.
