0.2 ilmenite an important ore of titanium is used in the production of ferro-titanium and other industrial products. in order to determine correctly the chemical composition of ilmenite need was felt to prescribe standard methods of chemical analysis so that these may primarily serve as referee methods and may also be used by laboratories..
For example, the ilmenite of the massive ores is the highest in mgo and tio2 and the lowest in feo, fe2o3 and mno, whereas the ilmenite of the gabbro has opposite compositional characteristics. mgo content of the ilmenite and magnetite has a significant positive correlation with forsterite content fo .
