Abstract


       The  present paper is concerned with the actual problem  - all-round application of the mineral part of the native coals. The ash-slag wastes derived from coals are characterised as nontraditional raw materials of the rare metals. Some chemical and technological problems of scandium extraction from coal ashes are considered.
