Mamiya, Mitsuo published the artcileFundamental study on the flotation separation of iron hydroxide and gypsum precipitated in the neutralization process. II, HPLC of Formula: 2016-56-0, the publication is Nippon Kogyo Kaishi (1982), 98(1132), 501-5, database is CAplus.
Flotation was applied for the separation of Fe(OH)3 and gypsum formed in neutralizing the acid drain from an Fe sulfide mine by CaCO3 or Ca(OH)2. The flotation of precipitate obtained from the water containing 1 g Fe3+/L and 6 g SO42-/L was by dodecylammonium?acetate??[2016-56-0]. The selectivity was affected by the rate of neutralization. Satisfactory results were obtained only when the aging process was introduced in the neutralization at pH 2.9. Starch acted as a selective flocculant as well as a depressor for Fe(OH)3, and gave satisfactory selectivity even when a rapid neutralization was adopted. These flotation products are upgraded by washing with small volume of water or an acidified saturated solution of gypsum.
