| Abstract: | The best condition and design of the experiment are studied in determining the micro silver in gold concentrate,rare metals,non-ferrous metals,tailings and other different ores by the dithizone spectrophotometry,in which the sulfide ores are dissolved by HCl-HNO_3-Br_2(l) system.Results show that the method has the advantages of simplicity,rapidly,sensitivity and accuracy,and it has been successfully applied in determination of silver with satisfactory results. |
