Iron sand is a type of sand with a significant concentration of iron. It is usually dark gray or blackish in color. The sand consists of magnetite, Fe3O4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium. Iron sand has a tendency to heat up in direct sunlight, causing a high enough temperature to cause minor burns.

Iron sand is mainly derived from basaltic and volcanic andesitic rocks. Generally widely used in industries such as steel mill materials, and magnetic materials by taking iron ore, ceramics factory, cement factory and refractory materials by taking silicate (Austin, 1985).

Although in recent years iron sand intensive cultivated, but there is still a chance to find new potential. In addition, with the development of mining and processing technology, as well as increased demand, the relatively low grade iron sands which were not cultivated in the past because they have no economic value, will have the opportunity to be cultivated in the future.
