| Abstract: | The nickel sulphide fire assay method is adopted to extract the platinum group elements intoa nickel sulphide button. Then the button is dissolved in 6M HC1 and the solution is fitered. The residusof the platinum group elements is analyised by neutron activation analysis. This method has better ac-curacy and precision. Its detection limits are about the ppb level. |
