ABSTRACT:
Method and apparatus for reducing the quantity of carbon dioxide emitted to the atmosphere from carbothermic processes producing metals are described. The method involves rejecting carbon from the process system or using carbon as a reagent to be recycled within the boundaries of the process system as a result of reactions of hydrogen with the carbon monoxide produced by the carbothermic process. Examples of the application of the method are given for the production of aluminum and for the production of a portion of the iron content of steel.
