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