FIELD: mining.
SUBSTANCE: method involves preliminary oxidation of carbonaceous substance of the sample with further traditional metal oxidation with mixture of concentrated chlorhydric and nitrogen acids by conversion to chlorides and determination of gold, platinum, palladium and silver in final solutions; at that, preliminary oxidation of carbonaceous substance of the sample is performed with mixture of nitrogen acid with hydric dioxide in the ratio of 10:1 in microwave system of microwave-frequency mineralising agent under pressure of 7-8 atmospheres with simultaneous autoclave treatment during 10-30 minutes.
EFFECT: simplifying, accelerating and increasing informativity of the analysis.
