Gallium is a chemical element; it has symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, gallium is in group 13 of the periodic table and is similar to the other metals of the group.The results show that gallium concentration is as high as 44.8 μg·g −1 in the whole coal-channel sample, and varies from 30.1 μg·g −1 to 76.0 μg·g −1 (mean 51.9 μg·g −1) in the main minable benches of No.6 Coal. Such high concentration of Ga in the coal is far higher than the industrial grade (30 μg·g −1 ).Discovery of the superlarge gallium ore deposit in Jungar, Inner ...Gallium is a chemical element; it has symbol Ga and atomic number 31. ...
