摘要： A first method for producing an improved coal which comprises heating and aging a low quality coal in an organic solvent to produce an improved coal for use in metallurgy having enhanced softness and fluidity as compared to the low quality coal; and a second method for producing a reduced metal and a slag containing an oxidized nonferrous metal, which comprises preparing granules from a mixture of the improved coal and a raw material containing the oxidized nonferrous metal, heating and reducing the granules in a moving hearth furnace, followed by successive heating and melting, to form a reduced molten product, cooling and solidifying the reduced molten product in the moving hearth furnace to form a reduced solidified product, withdrawing the reduced solidified product out of the furnace, separating and removing a slag with a screen, and recovering a metal component as a reduced metal. The first method allows the reforming of a low quality coal, which can not be used in the production of a reduced metal through a conventional carbon composite method, into an improved coal for metallurgy suitable for use in the carbon composite method, and the second method can be used for producing a high quality reduced metal by the use of the above improved coal as a coal to be incorporated inside.
