Abstract
Lightweight and reactive metals can be produced from ore, refined from alloy, and recycled from metal matrix composites using electrolysis in electrolytes including an ionic liquid containing a metal chloride at or near room temperature. Low electric energy consumption and pollutant emission, easy operation and low production costs are achieved.
