In the report (1), the methods for determination of the total Fe, TiO2 and FeO in sand iron and ilmenite were developed. In this roport, a simple spectrophotometric methods is described for the determination of SiO2, Al2O3, V2O5 and Cr2O3 which are contained in sand iron and ilmenite. SiO2 is determined by the molybdenum blue reaction. Al2O3 is determined by the oxinate extraction method. V2O5 is determined by the H2SO4 method. Cr2O3 is determined by the diphenylcarbazide method.
