NOVELTY - A method involves providing a source of each of steam, oxygen gas and chlorine gas, gasifying a carbonaceous source using the steam and oxygen, and producing a gaseous hydrogen output and a gaseous carbon monoxide output. Carbochlorination is performed on an ore containing metallic components using chlorine gas and gaseous carbon monoxide, and a heterogeneous output stream and a gaseous carbon dioxide output are obtained. The heterogeneous output stream is processed, and metal chlorides are segregated into homogeneous metal chloride output streams and a byproduct carbon dioxide stream.    USE - Method for provision of fuel for performing zero-emission power generation, metallurgical reduction, and carbon oxide management to mitigate greenhouse gases.    ADVANTAGE - The method enables performing zero-emission power generation, metallurgical reduction, and carbon oxide management to mitigate greenhouse gases in an economical and effective manner.    DETAILED DESCRIPTION - A method involves providing a source of each of steam, oxygen gas and chlorine gas, gasifying a carbonaceous source using the steam and oxygen, and producing a gaseous hydrogen output and a gaseous carbon monoxide output. Carbochlorination is performed on an ore containing metallic components using the chlorine gas as a reactant and the gaseous carbon monoxide as an oxygen sink, and a heterogeneous output stream containing several metal chlorides and a gaseous carbon dioxide output are obtained. The heterogeneous output stream is processed in a manifold fluidized bed reactor, and the metal chlorides are segregated into homogeneous metal chloride output streams and a byproduct carbon dioxide stream, where each homogeneous metal chloride stream corresponds to one of the metallic components. The homogeneous output streams are passed into containers, such that each container contains a segregated metal chloride. The gaseous carbon monoxide and carbon dioxide generated by the gasifying and carbochlorination steps are managed by passing the carbon monoxide output from the gasifying step to the carbochlorination step as the oxygen sink, converting the gaseous carbon dioxide output from the carbochlorination step into a methane pool augmentation output, an elemental carbon output and a chemical synthesis output, and consuming the elemental carbon output in a manufacturing process. A portion of the gaseous hydrogen output is consumed in a power generator step, and another portion of the gaseous hydrogen output is consumed in a chemical synthesis process, where the integrated system and the power generator step are essentially free of greenhouse gas emissions.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a gasifier feed preparation process subsystem.
