Ore deposits that are close to the surface are mined by surface mining. In surface mining, any overlying rock is blasted away. The rock that contains the valuable minerals is placed in a truck and taken to a refinery. Specific methods of surface mining include openpit mining, strip mining, mountaintop removal, and placer mining.

Silica Sand Process * Silica sand is procured from the earth's surface by using surface mining techniques or the openpit operation process. Our range of silica sand is produced through dredging and underground mining are also employed to get the silica sand deposits.
