Sand mining - Wikipedia
Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river beds.Sand is often used in manufacturing, for example as an abrasive or in concrete.It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.Sand can replace eroded coastline.
