    Sand and Gravel Processing

    Mining by dredging involves mounting the equipment on boats or barges and removing the sand and gravel from the bottom of the body of water by suction or bucket-type dredges. After mining, the materials are transported to the processing plant by suction pump, earth mover, barge, truck, belt conveyors, or other means.

    Impacts of Sand Mining

    Minimization of the negative effects of sand-and-gravel mining requires a detailed understanding of the response of the channel to mining disturbances. Decisions on where to mine, how much and how often require the definition of a reference state, i.e., a minimally acceptable or agreed-upon physical and biological condition of the channel.

    How sand is made

    The following steps are commonly used to process sand and gravel for construction purposes. Natural decomposition 1 Solid rock is broken down into chunks by natural mechanical forces such as the movement of glaciers, the expansion of water in cracks during freezing, and the impacts of rocks falling on each other.

    Sand Extraction

    Besides changing the channel form, the legacy of mining sand and gravel in rivers and floodplains includes a preponderance of lakes and water bodies. In areas of rapid sedimentation, there are potential positive effects, including reduced flood stages and related damages, such as on rivers in China ( deLeeuw et al., 2010 ).
