Mining Techniques for Sand & Gravel | Sciencing
Sand and gravel must be sorted by size. This generally begins when it arrives for processing. Bars are placed over a receiving hopper to catch large pieces. Screens are then used to separate larger and smaller pieces as the materials are transported by belts or conveyors. The gravel is washed and either further processed or stored.
