Abstract
A method of refining magma, which includes silicon carbide, basaltic clay, and other insoluble components, including the steps of blending the magma with monovalent alkali hydroxides and a chemical oxidizing agent, melting the magma, and injecting oxygen into the melted magma. The melted magma is electrolyzed to separate metals contained in the melt, which are recovered by gravity separation followed by centrifugation. Soluble silicates are recovered by crystallization.
