The fire assay enrichment method was adopted to enrich precious metal granulation and to select the silver content measurement method from the Volhart method or potentiometric titration method according to actual conditions.Condition tests were carried out separately for sample weight,soot-blowing temperature,agent addition amount,and so on,and finally,it probed the best experiment conditions for the detection of platinum and palladium-bearing copper matte.Using the addition standard recovery rate to verify the method's accuracy,its addition standard recovery rate is 99.39％～99.77％,and the relative standard deviation is 0.48％～1.28％.Finally,a scientific and practical analysis method with high accuracy was established,it has great guiding significance for daily detection.
