ICP Spectrographic Determination of Platinum Metals and Gold by Using Powder Sample after Fire Assay Concentration |
| |
| Abstract: | This paper deals with the fire assay concentration and ICP spectrographic
methods for analyzing trace platinummetals and gold in copper and nickel
sulphide minerals.
Samples were treated by sulphur and stibium assay concentration.The
stibiuni buttons were subjected to cupellation until a diameter of some 1 .5 mm
was obtained.Some stibium powder was added to the buttons, and ground to
200-300 mesh.They were analyzed directly with an ICP automatic spectromet-
er. |
