Distribution of Industrially Valuable Trace Elements Associated with Germanium in the Coals of the Pavlovsk Deposit (Spetsugli Section)

Abstract

The concentrations and distributions of industrially valuable trace elements associated with germanium in the coals of the Spetsugli section of the Pavlovsk brown coal deposit in Primorskii krai was studied using mass spectrometry and laser microanalysis. The concentrations of a number of metals in traditional types of ores at a minimum industrial level were established. Geochemical associations of industrially valuable metals and other impurity elements were identified. Maximum concentrations of many trace elements in low-ash coals were noted. The distribution of a number of trace impurity elements in the coal matter and the macerals of coals was studied, and conclusions on the genesis of trace elements were drawn.
