METHOD FOR QUALITATIVE AND QUANTITATIVE DETERMINING ORGANIC COMPOUNDS OF PRECIOUS METALS IN VARIOUS COMPOSITION ROCKS

A method is proposed for preparation of a sample of various rocks, containing organic compounds of precious metals (such as Au, Pt, and Pt). The sample is usable for further analysis of the metals content. The sample being analyzed is mixed with potassium chloride or sodium chloride in a ratio of 5-...

Zusammenfassung:A method is proposed for preparation of a sample of various rocks, containing organic compounds of precious metals (such as Au, Pt, and Pt). The sample is usable for further analysis of the metals content. The sample being analyzed is mixed with potassium chloride or sodium chloride in a ratio of 5-to-95 percent, and further subjected to assay fusion with litharge. The resulted entrapped cold shot is dissolved in aqua regia, and its dilute solution is analyzed by the known atomic-absorption method or by the known method of atomic emission with the use of plasma fixed by induction. This method makes it possible to preserve maximum of the metal components being analyzed, whereas the traditional methods of sample preparation cause loss of the most part of organic components containing the precious metals.
