A method for the determination of silicon oxide,ferric oxide ,titanic oxide in bauxite by ICP-OES was reported. In this paper a method of working curve fitting with standard reference materials and the determination of several analytical line of the same element at the same time to correct the analytical line interference,matrix interference,background interference etc was applied .The recoveries of the method for the 3 elements are 97.9%--104.9% and the RSD（n=9） are 1.1%--3.7%.The method has been verified by analyzing the National Standard Reference materials and the results are agreement with certified values.
