Ilmenite is found in the form of iron sand with reserves of 927 315 827 tons spread across several regions in Indonesia including Banten which has seven million tons of iron sand This mineral can be used as a raw material for making TiO 2 pigments The problem faced in the use of Ilmenite is its complex mineral structure which causes
This research has been done to determine the content of TiO 2 from iron sand of Lampung by the acid leaching method Previously iron sand was mixed with sodium hydrogen carbonate NaHCO 3 and roasted at 700°C for an research used five samples to determine the TiO 2 content of Lampung s iron sand with variations in HCl concentration of 4
and processing of zircon and titanium dioxide products ilmenite rutile and upgraded titanium dioxide products of synthetic rutile slag and upgraded slag The two product categories have different properties prices and distinct end use markets Mineral sands deposits typically contain both
Moreover titanium dioxide is also used as an ingredient in a memristor a new electronic circuit element Synthetic single crystals and TiO 2 films are used as semicon ductors and also in Bragg stack force dielectric mirrors due to its high refractive index reaching [4] One of the ingredients of iron sand is titanium dioxide In
The three main chemical contaminates in silica sand are usually the iron content expressed as Fe2O3 the alumina content expressed as Al2O3 and titanium expressed as TiO2
Iron sand collected with traditional gravity separation method contained 8 to 12% TiO2 while iron sand collected with modern magnetic separation method contained less than 5% TiO2
