Rare Metals in Kuzbass Ash and Slag Wastes: Prospects of Extraction

Abstract

Kuznetsk coal basin is one of the largest and most promising basins of the Russian Federation. Deposits of Kuzbass coal are complex ore-coal deposits, containing industrial concentrations of goal, platinum, rare metals in coals, waste coal and bottom ash waste, the extraction of which creates products with high additional coast. In this paper the composition of bottom ash waste (Kemerovo, Leninsk-Kuznetsk, Mezhdurechensk) and methods to extract valuable components from them and the main areas to use them are given. The incentives, allowing ash disposal areas of power plants to be put into production as quick as possible, because they can contain significant stocks of valuable rare, dispersed and rare-earth elements, are justified.
