Mamiya, Mitsuo published the artcileSelective flotation of zinc hydroxide from gypsum precipitated in the neutralization process, Name: Dodecylamineacetate, the publication is Nippon Kogyo Kaishi (1986), 102(1186), 859-64, database is CAplus.
Floatability tests for Zn hydroxide and gypsum, both chem. precipitated, were carried out by using dodecylammonium acetate or Na dodecylsulfate as a collector with or without addition of soluble starch or Na silicate as a depressant of Zn hydroxide. Both precipitates are relatively floatable with either collector at pH 7-12, without depressant addition The addition of Na silicate depressed Zn hydroxide when Na dodecylsulfate was used. Selective flotation of gypsum from the mixture of both precipitates was successful by depressing Zn hydroxide with Na silicate. For synthetic mine water containing Zn2+ 1000, SO42- 7328, and Ca2+ 603 mg/L, the lime precipitation-selective flotation method was investigated, with 90% gypsum recovery in the froth and 87% recovery of Zn hydroxide in the tailing solution
