High Grade Zircon Sand Is Largely Used In Foundry As Mould

The high grade zircon sand is largely used in foundry as mould. It does not wet the molten metal, thus giving a better and smoother surface to the casting. It is estimated that about 75% of the total world zircon production is used as moulding sand and in the manufacture of refractory bricks, zirconium compounds and ceramics. Only 25% is used .
