<p>This invention relates to a method for assaying an ore sample to determine the concentration of gold and PGMs therein. The method comprises the steps of preparing an ore sample, combining the prepared ore sample with a lead-containing flux, inductively heating the combination (typically at a predetermined reference temperature profile) to form a fusion of slag and lead containing the gold and PGM's in the sample and separating the lead from the slag. The invention also covers a new flux for the process, the flux containing sodium hydroxide, a container for mixing the flux and an ore sample and an apparatus for separating molten lead from slag.</p> |
