ABSTRACT:
A method for separating non-ferrous metals from an iron-containing waste material which includes providing separate contiguous layers of the waste material and a sintering mixture containing a finely divided carbonaceous fuel, passing hot combustion supporting gases, first through the layer of sintering mixture and then through the layer of waste material in a sintering zone under conditions sufficient to sinter the iron containing constituents, and volatilizing off the non-ferrous metals to produce a charge suitable for feeding to a blast furnace.
