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. A dredge is placed in the lake to extract the aggregate from the pit; the material is then carried by running
· Sand mining is the process of extracting sand from an open pit, sea beaches, rivers and ocean beds, river banks, deltas, or inland dunes. The extracted sand can be used for various types of manufacturing, such as concrete used in the construction of buildings and other structures.
