The recovery of gallium from a Virginia feldspar ore
Abstract
dc:description.abstractA method of extracting gallium from a Virginia feldspar has been determined. The steps in this method are: 1. Grinding of the ore to a very small particle size (200 mesh) 2. Extraction of gallium by “leaching” the ore with sodium hydroxide 3. Acidification of the sodium hydroxide solution with hydrochloric acid and subsequent extraction of the acid solution with ether to separate the gallium from aluminum, vanadium, and titatium, and other metals 4. Removal of iron by precipitation of ferrous sulphide with hydrogen sulphide 5. Precipitation of gallium by cupferron 6. Ignition of the cupferron precipitate to gallium oxide
