Noble metals of the Albynsky gold ore field in the Upper Amur River region

Abstract

The contents of noble metals (Ru, Rh,Pd, Ag, Os, Ir, Pt, Au) on the Albynsky gold ore field of the Upper Amur River region are given in geochemical objects: ores, overburdens, plants, surface waters. To this end, the methods of atomic absorption, voltammetric, catalytic, photocolorimetric and chemical analysis methods were used, by means of the assay and extraction concentration methods for determining the mass fractions of noble metals in ordinary geochemical samples with error in correctness, accuracy and reproducibility of the result ≤ 30%. In the obtained series of geochemical abundance of noble metals, the influence of seasonal permafrost was noted. It was established that there is no connection between the low-temperature hydrothermal genesis of the gold ore field and the concentrations of platinum group metals.
