Worldwide, extraction of silica sand is almost exclusively done by surface quarrying. The mine in Lochaline is the only underground sand mine in Europe. The huge deposit of pure white sandstone is extracted by using a room and pillar method. The sandstone is drilled, blasted, loaded into dump trucks and taken to the surface plant, where it is crushed, washed, screened, scrubbed and spiralized ...

sand and sandstone. Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant. Figure is a flow diagram for industrial sand and gravel processing. The mined rock .
