Sandstone | Minerals Education Coalition

Once blasted, the sandstone is “mucked” using a front-end loader, placed into haul trucks, and transported to a primary crusher. Following crushing, the material may report to a secondary or tertiary crushing plant. The sized material is then transported to a processing plant, usually by a conveyance system.

Sandstone - Wikipedia

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in Bowen's reaction series. Like uncemented...
