Sand and Gravel Mining Process. Once an aggregate deposit is found, the first step in extracting the sand and gravel is to clear the surface of vegetation and topsoil and dig a pit. Since the water table is so close to the surface in Nebraska, the pit fills with water and forms a lake.
Worldwide, more sand and gravel is mined annually than any other industrial raw material. Preliminary estimates of sand and gravel production in Arkansas for 2007 by the U.S. Geological Survey are nearly 9.1 million metric tons valued at $66,300,000. Nearly fifty percent was used for concrete aggregate and concrete products.
