Abstract
The technology presented permits to use different coal ranges, to solve the problem of ash utilization and significantly reduce emission of toxic elements into the atmosphere and at the same time produce metals and their concentrates. The main product is fine coal which can replace fuel oil and motor fuel. The flow chart of chemical purification of fine coal consists of 5 main stages: breakage, kilning in boiling bed, leaching, microwave irradiation and production of the water-coal mixture.
