Abstract
The results of a study of lignite samples from the Serchanskoe deposit are presented. It was established that lignite in different sections of the deposit differed in terms of ash content and germanium content. The germanium content varied in a range of 5265–6900 g/t on an ash basis. The yield of free humic acids from lignite was insignificant (no higher than 1.5% on a dry ash-free basis). Germanium in lignite is concentrated in the organic matter.
