determination of trace amounts of silver in galena ores

in galena ores, based on the "reversion" of silver dithizonate. Silver is separated from relatively large amountsof lead by extraction as dithizonate into chloroform from an aqueous 1:99 nitric acid solution. Separation from mercury, which is also extracted under these conditions and would, if present, interfere in the analysis,
