Zircon Sand is generally found inland of ancient coastlines, some of which can be found very far inland, where the heavier mineral sands formed hardened deposits. These deposits are typically mined via dry or wet (dredge) mining techniques.

Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke added industrial salt.
Black Silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke.
Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.
Tabular alumina is a kind of pure sintered corundum,which is sintered and completely shrink without adding any additive,such as MgO or B2O3,with coarse crystals and well-developed Al2O3 crystal structure.
Boron carbide is a compound that contains boron and carbon, especially B4C; an extremely hard, non-metallic, black crystalline compound or solid solution.
Garnet sand is a kind of mineral with good hardness and widely used for abrasives, refractory material, sandblasting and waterjet cutting,etc.
