The northern regions of the Arctic zone of Yakutia of the Republic of Sakha (Yakutia) are the most industrially developed region of the Republic. Tin and tungsten ore deposits were mined in the region from 1938 to 1993. The waste from the ore enrichment of these metals accumulated in tailings ponds in the immediate vicinity of processing plants. The tailing dumps contain components that were not extracted and unclaimed by the industry at that time, and therefore their extraction technology was not developed. They are technogenic deposits of a complex type containing various minerals present in primary ores of various minerals types.
