Abstract
Recycling methods and apparatus produce elements of high purity from diverse feedstock materials melted in an electronically conductive liquid. Distinct anodes are used in respective circuits configured for electrorefining and electrowinning. The electrorefining circuit is operable to produce an element in a gaseous state. The electrowinning circuit includes a SOM anode, allowing feedstock materials incorporating significant oxide constituents to be recycled. The methods and apparatus are suitable for magnesium recycling.
