  • Foundry Sands and Coatings Zircon Industry Association

    Zircon is widely used in the foundry industry, mostly in the form of SAND and FLOUR (milled sand) for casting and refractory applications. Zircon’s properties make it ideal as a moulding base material for sand casting and investment casting, in addition to use as mould coating in die casting and in refractory paints and washes to reduce the wettability of other foundry sands.

  • 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.
