The Extraction of Gallium from Zinc Ores CaltechTHESIS

The discovery of small amounts of gallium in zinc ores showed the possibility of its presence in a small quantity of zinc ore residues on hand at the Institute. Germanium had been previously extracted from the ore, and later, part of the zinc was recovered. During this work, the presence of gallium was shown by spectroscopic tests, and indium was at the same time shown to be absent.</p> <p>In

Separation of gallium and arsenic in wafer grinding

Well separation between gallium and arsenic was performed in both laboratory and pilot tests. Hydrophobic membrane polytetrafluoroethylene (PTFE) with 0.2 microm pores was the best of three membrane supporters. The most efficient separation was obtained using an acidic feed (pH at 1.8) with 1000 ppm gallium. Over a 12-h period of stripping, the striped Ga concentration increased with the

Preferential extraction of gallium from Bayer liquor using

Gallium extraction studies were carried out using resin containing an hydroxamic acid functional group. Extraction was dependant on reaction time and alkali concentration. The resin did not extract aluminium. Vanadium extraction kinetics were slower than those of gallium.
