Mining Techniques For Sand

  • Mining Techniques for Sand & Gravel Sciencing

    Other Sand Mining Methods Sand dunes can also be mined by dredging or hydraulic methods. This involves a high pressure jet of water to wash the sand into a pond where it is pumped to a storage pile or tank. Where sand is present in the form of loose sandstone, drilling and blasting are necessary.

    OverviewBy countrySee alsoExternal links

    Sand mining is the extraction of sand, mainly through an open pit (or sand 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. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.
