摘要：

A system for separation of trace impurity elements (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Pt) from large amounts of matrix element gold is proposed in this paper. It is based on the MIBK extraction. The effect of pH to the extraction is studied, the final measuring solution is effectively 10 % hydrochloric acid. The recovery of elements is between 93.3 % -100 % under this acidity after the first extraction. Content of trace elements of 99.99 % gold is in the range 0. 1-20 mug.g(-1).
