EP0283740A2 - Oxidative dissolution of gallium arsenide ...

Gallium is recovered from gallium arsenide by reacting and dissolving the gallium arsenide with an oxidant and a com­plexing agent, especially with water insoluble hydroxamic acids with mild conditions, e.g. with aqueous hydrogen peroxide and mild temperature, to effect separation of gallium hydroxamic acid chelates from water soluble arsenic compounds. The separation and recovery of gallium and indium from zinc refinery residue, using liquid−liquid extraction, has been investigated. The major components with the exception of zinc can be removed by extraction with tri-n-butyl phosphate at low aqueous acidity, and gallium and indium can be separated from the remaining major component, zinc, by extraction with bis(2-ethylhexyl)phosphoric acid ...
