Gravel Mining Process Description

Once an aggregate deposit is found, the first step in extracting the gravel is to clear the surface of vegetation and topsoil and dig a pit. Since the water table is so close to the surface, the pit fills with water and forms a lake. A dredge is placed in the lake to extract the aggregate from the pit; the materials are then carried by running water to a separator which separates the material by particle size. Different applications require different particle sizes, but typically, more fine sand is produced than can be sold. This excess sand is pumped back to the lake through a discharge or slurry pipe, forming the sandy nesting areas used by terns and plovers. In areas where most of the natural nesting habitat has been lost on the river, gravel mines play an important role in the conservation of terns and plovers.
