Iron sand is known as one of the sources of TiO2 in the form of ilmenite or titanomagnetite mineral. Iron-titanium oxide mineral contained in Indonesia iron sand are classified as titanomagnetiteThe iron is precipitated as hydrated iron oxide from the synthetic rutile grains and a mild acid treatment is used to dissolve the impurities and any residual iron. The grains of synthetic rutile are washed, dried and transported to titanium dioxide pigment manufacturing plants either in Australia or overseas for further processing.Titanium Geoscience Australia

Magnetic Separation and Enrichment of Fe–Ti Oxides from Iron
Iron titaniferous sands, also called black sands, are a source of various magnetic minerals, such as iron and titanium (Fe–Ti) oxides, with countless scientific and industrial applications. Ecuador is deemed a geo-diverse country that contains deposits of black sands in the Andean and coastal regions; therefore, the industrialization of these magnetic sands The titanium-containing phases in the slag system are: black titanium, TiO 2, Ti 2 O 3, a small amount of titanium iron oxide, TiCN, TiC and some magnesium aluminum spinel.

After iron impu-rities were removed by ion exchange, 4% NH 4 (OH) was added to precipitate the amorphous titanium. This precipitate was then calcined at 900°C, thus obtaining the purified TiO 2 of rutile structures.Successive Methods for the Separation of Titanium

An iron sand concentrate was pelletized and reduced using coal under the isothermal–temperature gradient profile with a controlled heating rate starting from 1000 °C to a final temperature of 1180–1380 °C. Each pellet was a non-composite mixture, where coal as a reductant was added to cover the whole surface of the pellet. The visual Black mineral sands are widely used to obtain titanium dioxide, titanium, and, more recently, a variety of iron–titanium oxide nanostructures. Highly corrosive mineral acids or alkalis are commonly employed for this purpose. Hence, it is desirable to find eco-friendly ways to process these minerals, deriving high-added value materials.
