Abstract

Extracting gallium and/or arsenic from materials comprising gallium arsenide is generally disclosed. In some example embodiments, a material comprising gallium arsenide may be exposed to a first heating condition to form a first exhaust. The first exhaust may be directed to an arsenic collection bed including aluminum, which may form aluminum arsenide. The material including gallium arsenide may be exposed to a second heating condition and/or a vacuum may be applied, which may form a second exhaust. The second exhaust may be directed to a gallium collection bed including aluminum, which may form gallium alloys of aluminum.
