An analysis method for determination of gold, platinum and palladium in copper slag by inductively coupled plasma atomic emission spectrometry (ICP-AES) with tellurium co-precipitation separation and enrichment was developed. The factors affecting determination were investigated, and the optimal detection conditions were determined. The detection limits were 5.6 (Au) μg/L,8.2 (Pt) μg/L and 3.6 (Pd) μg/L, the recovery ratio was 93.2%~102%, the relative standard derivation (RSD) was 1.21%(Au)~3.45% (Pt). The determination results were in good agreement with fire assaying. The method was accurate, simple and fast, and easy to master.
