Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or d 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. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.选择时，新内容将添加到焦点当前区域上方
