Abstract: This invention relates to a method and a reactor for gasifying a carbonaceous feedstock material. The method includes the steps of choke-feeding a carbonaceous feedstock material into a pyrolysis zone of the reactor to form a discharge bed; heating the discharge bed to initiate pyrolysis of the feedstock material to form a pyrolysis product; providing a lower lying upper oxidation zone; gasifying the pyrolysis product to form a bed of char; converting thermal energy into chemical energy in an upper reduction zone; providing a lower lying lower oxidation zone; collecting any metal slag and/or slag melts in the lower oxidation zone; and discharging hot reducing gases having a temperature of at least 1300° C. and a CO/CO2 ratio of ?5, more preferably ?15.

Abstract: The present invention relates to a process for the smelting of a metalliferous feedstock material. The process includes the steps of: (i) feeding an agglomerate comprising of a fine metalliferous feedstock material and a fine reductant to a reactor, the agglomerate forming a packed bed within the reactor; (ii) smelting the agglomerate by passing a hot reducing gas counter current through the packed bed to form a molten material comprising a partially reduced metalliferous constituent, an intermediate slag constituent and entrained unreacted reductant constituent; and (iii) channelling the molten material to flow into a vessel to form a metal product and a slag product.
