Copper lead-zinc ore sample was added nitric acid, hydrochloric acid, hydrofluoric acid, perchloric acid in the cup after blocking digestion process, coupled with smoking sulfuric acid, hydrochloric acid, extraction, dilution inductively coupled plasma mass spectrometry (ICP-MS) Determination of rare earth elements which, with rhodium and iridium as internal standard element of the compensation matrix effect and sensitivity drift. Reference substance (GBW07233 ~ GBW07237) copper lead-zinc ore in accordance with standard analytical accuracy and precision of the results of the evaluation method, the measured value of the standard material consistent with the standard value, relative standard deviation (RSD) of 1.2% ~ 7.6% meet regulatory requirements in geological samples analysis. The detection limit of 0.001 ~ 0.011μg / g.

Nitric acid, hydrochloric acid, hydrofluoric acid (HF) ammonium perchlorate decomposition of the sample, determined the amount of renewable raw materials zinc copper, lead, iron, indium, cadmium, arsenic, calcium, aluminum by inductively coupled plasma atomic emission spectrometry . The measurement range: ω (Cu): 0.01% ~ 0.60%; ω (Pb): 0.10% ~ 5.00%; ω (Fe): 0.10% ~ 5.00%; ω (In): 0.0100% ~ 0.200%; ω ( Cd): 0.010% ~ 3.00%; ω (As): 0.10% ~ 2.00%; ω (Ca): 0.10% ~ 10.00%; ω (Al): 0.10% ~ 4.00%. The recoveries of the elements is 93% to 113%. The method is accurate, fast, reliable, suitable for regeneration of copper, lead, iron, indium, cadmium, arsenic, calcium, aluminum, zinc Simultaneous Determination of the amount of raw material.
