Abstract

Valuable trace element distribution in ash formed upon burning coal from the Ekibastuz Coal Basin was studied using up-to-date analytical methods. Problems in the recovery of valuable trace elements are due to their low concentrations, the presence of caked aggregates of particles of varied mineral origin and irregular trace element distribution in ash.
