Abstract: The separate measurement of potassium, sodium, copper, zinc and lead in the standard analysis method is modified to bulk measurement. High grade imported iron ore sample is dissolved with HCl+HF+HNO3+HClO4, and the contents of the five elements in the iron ore are continuously measured by air-acetylene flame atomic absorption spectrometry method (FAAS), which is accurate, reliable and practically feasible.
