Abstract
The energy strategy of Russia’s development by 2030 provides for an increase in the volume of coal production, while a large proportion of these coals are subject to enrichment and processing in order to obtain high-margin products. Also, on the modern path of development of coal-processing industries, a great potential is associated, firstly, with the processing of coal enrichment waste and generating income through the production of relevant products; secondly, reducing the environmental burden from the placement and storage of such waste and thereby reducing environmental costs. The article presents a model experiment on nitric acid dissection of coal enrichment waste at the Berezovskaya Research Center with subsequent extraction of rare and rare-earth metals with tributyl phosphate from the obtained solutions. The experiment was carried out with the waste of coal enrichment of the Berezovskaya COF after heavy-medium separation and hydrosizers. The scheme of waste processing is given and the method of conducting the experiment is described, which specifies the conditions of the processes (temperature, contact time, the fraction of the introduced component, the speed of rotation of the agitator). The opening of the waste with nitric acid followed by extraction of rare-earth metals with tributyl phosphate, carried out on a model system, made it possible to completely extract the introduced lanthanum (III) oxide. The obtained samples were examined on an X-ray fluorescence spectrometer.
