Abstract

Data on the concentrations of trace elements in coals and coal ashes from productive beds I and II of the Mugunsk deposit (Irkutsk coal basin) are presented. The mineral composition of the test samples is given. It was found that the concentrations of Sc, Ti, and Sr reached minimal commercial contents. Mineral carriers of the trace elements are proposed.
