20tph silica sand washing plant

This silica sand washing plant project is a high purity quartz sand production line.

Our company conducts repeated experiments on the raw silica sand, and finally determines to adopt pickling process after the roughing of flotation process.

The pickling process greatly improve the purity of quartz sand. The whole pickling process is carried out in the closed special equipments without any pollution to the environment. Through pickling, and the final content of silica is greatly improved, reaching 99.92%.The iron content is under 20ppm which meets the requirement of high purity quartz sand.
