Ga(OH)3, which was conventionally obtained as a residue of Zn hydrometallurgy, floated completely in water with a collector of Na dodecylsulfate (SDS) at pH 4-7.0 and did not float entirely with a dodecylammonium acetate (DAA) collector in the same conditions, while Ga(OH)3 in an aqueous solution saturated with gypsum floated to some extent with either of the collectors. Because gypsum was quite floatable in these conditions, some depressants for the selective flotation of Ga(OH)3 from gypsum were used and soluble starch and gum arabic were effective as a depressant for Ga(OH)3 in DAA flotation. When DAA was used as a collector and soluble starch or gum arabic was added as a depressant, Ga(OH)3 was effectively separated from gypsum and 91% of Ga(OH)3 was kept in the tailing.
