Based on a study on the make\|up and enrichment of Pt and Pd in Jinbaoshan ore by Pb assaying, a appropriate make\|up is put forward. With the level of silicic acid being 1\^0, for the concentrate, the make\|up contains 20 g Na\-2CO\-3, 50 g PbO, 5 g SiO\-2, 8 g Na\-2B\-4O\-7\510H\-2O and 3\^0 g flour, for the tailings, the make\|up contains 20 g Na\-2CO\-3, 50 g PbO, 10 g Na\-2B\-4O\-7\5H\-2O, 3\^5 g flour. This make\|up allows the sample's composition to vary in a large range and provides a high accuracy, with the recovery over 95%, relative standard deviation less than 3\^2%.
