Abstract
A method of producing metals and metal alloys from metal oxides is disclosed. The method comprises the steps of: (a) passing a gas at an elevated temperature through a bed of composite agglomerates that are formed from metal oxides and solid carbonaceous material and thereby reducing metal oxides in the agglomerates to metal and melting the metal; and (b) collecting the molten metal from the agglomerates.

A method of producing metals and metal alloys from metal oxides, which method comprises the steps of:
- (a) injecting metal oxides and a solid carbonaceous material into a molten bath in a smelter and reducing the metal oxides to molten metal and producing an off-gas;
- (b) passing the off-gas at an elevated temperature, as defined herein, through a bed of composite agglomerates that are formed from metal oxides and solid carbonaceous material and thereby reducing metal oxides in the agglomerates to metal and melting the metal;
- and
- (c) collecting the molten metal from the agglomerates.
