The Importance of Frac Sand Processing. The production of oil and natural gas from shale deposits relies on the use of proppants to maintain the openings induced by hydraulic fracturing. The most common proppants are produced from high quality silica and sand deposits and are known as frac sand.
Silica sand deposits are most commonly surfacemined 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. It is then dried and sized to produce the optimum particle size distribution for the intended application.
