    Silica Sand is quartz that over time through the work of water and wind has been broken down into tiny granules. Silica sand deposits are most commonly surface-mined in open pit operations but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. The process of silica sand mining processing plant is roughly divided into crushing grading scrubbing desilting and magnetic separation to maximize the purity of quartz sand. Due to the mature processing technology of the silica sand processing plant the quality of finished products is also high.
