The extraction of gallium from zinc ores

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.
