11.19.1 Sand And Gravel Processing - US EPA

2015-9-10  Industrial sand and gravel typically are mined from open pits of naturally occurring quartz-rich 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

2012-4-9  Gravel Mining Operations. Gravel mining operations on Wynoochee River being excavated by dragline, Courtesy: Kondolf, 1994. Operations include the wet excavation of riverbeds for gravels and the dry pumped excavation of floodplains. The advantage in the later method is the ease of excavation, whereas the pumping comes at a cost as well.
