Iron is a transition metal and one of the most abundant elements in Earths crust, being the only element to have an age named after it [1, 2].Such is the amount of iron in the terrestrial crust that it is supposed to have even influence on the atmospheric (hbox {O}_{2}) concentration [].. Regarding iron ore production, China, Australia, and Brazil are the top mining …

removal of this iron by leaching; and the relative increase in the concentration of impurity elements alters the original ilmenite [9]. The TiO2 content can even exceed the 60% when the ore is altered to leucoxene, which is a mixture of rutile or anatase amorphous TiO2 and iron oxides. In addition, ilmenite usually

Anorthite contains 19.4 percent aluminum and 20.2 percent silicon. It has been used commercially as an alurninum ore and will be used more and more in the future as the supply of bauxite declines. For titanium and iron, lunar ilmenite would be an excellent ore. Ilmenite contains 31.6 percent titanium and 36.8 percent iron.
