ABSTRACT:
The invention provides efficient and effective processes for recovering metals such as aluminum, magnesium and lithium from mixed waste sources such as auto shredder residue, aluminum cans, waste particles of aluminum alloy and municipal waste. The metal-waste source is dissolved in a more noble metal solvent at a temperature at which contaminants do not dissolve. The purified metal is then recovered from the solvent, preferably by electrorefining.
