Abstract

During the operation of thermal power plants, a huge amount of ash and slag waste is generated, which pollute the environment and are disposed of only by 10%. It is necessary to consider coal as a complex raw material. Kuzbass ash slags can be used to extract expensive rare and rare earth elements (REE), which significantly increases the profitability of the coal industry by obtaining both metals and functional materials based on them. The ash and slag wastes of the Kuzbass GRES and CHP plants were studied using optical emission spectrometry and inductively coupled plasma mass spectrometry. The data obtained indicate that the ash slags of Kuznetsk coal contain industrially significant conditions of many rare and rare earth metals or their contents are close to industrially significant.

Keywords

Coal, Coal wastes, Rare, trace and rare-earth elements, Ash and slag materials.
