The optimal conditions were investigated to the determination of W, Sn, As, Bi element in ores by inductively coupled plasma atomic emission spectrometry. The influence of major elements in matrix of samples were studied. Then the suitable condition had been found for establishing a specific process to identify these elements. Based on this principle, we study the optiman condition of the equipment as well as the factors which impact on spectrum of W, Sn, As, Bi elements in ore samples. From these, the reference lines and specified procedure can be established to determine concentration of W, Sn, AS, and Bi by ICP-OES method.
