Lead ore,lead concentrates and lead-zinc ore were prepared by microwave assisted digestion in a pressurized vessel mixed with HCI, HNO3 and HF. Ten components in sample solution including zinc, calcium oxide, sodium, hydroxide, manganese oxide, magnesiumoxide, arsenic, copper, cadmium, alumina and potassium hydroxide were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The optimum working conditions of the instrument was obtained. The powder was 1.3 kW. The plasma gas flow rate was 15 mL/min. The auxiliary gas flow rate was 0.2 mL/min. The sample uptake amount was 1.5 mL/min. The correlation coefficient of all elements was over 0. 9991 and the recovery rate was 91.3 %-109.7%.
