It is worth mentioning that Ga-bearing host minerals are rare. The majority of Ga is currently produced as a by-product of bauxite processing and the remainder produced from zinc-processing residues (Alonso et al., 2012, Frenzel et al., 2016, U.S. Geological Survey, 2017).The Ga production has been increasing at an average annual rate of 7.4% over the past …
