Studies of Collectors. Part 12. The Flotation of Gallium Ion with Polyphenol-type Surfactants

Polyphenol-type surfactants bearing 1,2-benzenediol or 1,2,3-trihydroxybenzene units were prepared and applied as flotation collectors for Ga(3+).The surfactants exhibited a lowering of surface tension at pH 11 (32-47 dyn cm-1.Gallium(III) was highly floated (80-90percent) at pH 3-8 with equimolar Cn-1H2n-1C(O)C6H3(OH)2 (n=8 or 12) or C7H15C(O)C6H2(OH)3, but not as highly (60percent) with C12H25S4.8(CH2CHCO2H)9.5H.The floatabilities of Ga(3+) in 1 mol dm-3 NaOH were 86-99percent, those in 3 mol dm-3 NaOH were 63-67percent, and those in 5 mol dm-3 NaOH were 26-39percent by using a six-fold molar excess of Cn-1H2n-1C(O)C6H3(OH)2 (n=12 or 18).On the other hand, the floatabilities from 1-5 mol dm-3 NaOH solutions when Cn-1H2n-1C(O)C6H2(OH)3 was added were nearly constant (58-59percent with n=12 and 31-35percent with n=18).The Ga(3+) in a Ga(3+)-Al(3+) mixture was floated selectively at pH3-5 by using C7H15C(O)C6H3(OH)2 or C7H15C(O)C6H2(OH)3.Moreover, the polyphenol-type surfactants in these flotation systems were almost entirely absent (-5 mol dm-3) from 3-5 mol dm-3 NaOH solutions and little decomposed.
