This paper, by means of experiments to study the application effect of determination method of alumina in several different ore, finally it is concluded that research results, think for acid vast ore samples of aluminum oxide content determination, icp-aes and engage method and edta complexometric DZG93-05 the effect of zinc acetate capacity method is more accurate and reliable, but when the alumina content in the ore is lower than 20%, icp-aes and engage method is not applicable, acid soluble method is more accurate, more secure on the universality of use to be promoted.
