The mineral zircon is mined for use as specialty foundry sands, abrasives, ores of zro2 and zirconium metal, refractories and zirconium chemicals. It is produced as one of several products from heavy-mineral sand deposits associated with ancient shorelines. Because of its low coefficient of thermal expansion, its high melting point, its high refractive index and its chemical inertness, it is an attractive refractory material. Zircon varies from deposit to deposit in terms of grain size, grain shape and chemical purity. Thus, there is a wide range of commercial zircon products that differ in impurity levels, particle shapes and grain sizes.

Sillimanite is a natural product and as such slight variations in the chemical analysis and size distribution should be expected. Special contracts covering guarantees other than those specified can be negotiated.

Garnet sand is a good abrasive which is used for water filtration and as a wood finisher for furniture pieces. As an abrasive, garnet can be divided into two categories: blasting grade and water jet grade. Garnet is crushed into finer grains and used for sand blasting. The larger grains after being crushed are used for faster work while smaller grains can be used for finer finishes. Garnet sand is brittle and can fracture easily which is the reason why different types of sand are produced.

Rutile is an interesting, varied and important mineral. Rutile is a major ore of titanium, a metal used for high tech alloys because of its light weight, high strength and resistance to corrosion. Rutile is also unwittingly of major importance to the gemstone markets. It also forms its own interesting and beautiful mineral specimens.
