May 10, 20160183;32;Frac sand mining is the mining of sand that is used in the fracking process to get oil and natural gas out of the ground.
Clean sand is stockpiled until it can be loaded into trucks for final sorting and drying off site. (Some mines sort and dry sand on site rather than sending it out.) Because the sand still contains moisture when it is stockpiled, drain tiles beneath the piles channel water to a lined process water pond.

Note there are several mining facilities in operation and several proposed that mine or would mine below the groundwater level utilizing hydraulic dredging to remove the sand. The overview of the sand mining process provided below is descriptive of a more common dry mine although
Sand and Gravel Mining Process Once an aggregate deposit is found, the first step in extracting the sand and gravel is to clear the surface of vegetation and topsoil and dig a pit. Since the water table is so close to the surface in Nebraska, the pit fills with water and forms a lake.

Sand mining presents opportunities to extract rutile, ilmenite and zircon, which contain the industrially useful elements titanium and zirconium. These minerals typically are found in ordinary sand deposits and are separated by water elutriation. Sand mining is a direct cause of erosion, and impacts the local wildlife.
If the sand deposit is below the water table and generally wet, it is best to mine it hydraulically. Dredge pump methods are widely used for such deposits. Summary of the Silica Sand Processing Plant Equipment. Silica Sand Washing Process Market Specifications.
