Abstract:
A method of the invention for treatment of particulate material for metal recovery includes heating a furnace to a first temperature, feeding a particulate material into the furnace, and before or after heating of the raw material, feeding a reducing gas flow through the furnace. The particulate material is heated in the furnace for volatilizing one or more metals contained in the ash into the gas flow, and the volatilized particles are recovered in one or more collection units.
