Xue, Yulan published the artcileFundamental study on the treatment of acid mine wastewater containing iron and sulfate ions by the neutralization-flotation method, Formula: C14H31NO2, the publication is Zhongnan Kuangye Xueyuan Xuebao (1982), 63-9, database is CAplus.
Artificial acidic mine wastewater containing 1000 mg Fe(III)/L and 6000 mg SO42-/L at pH 2.0 is treated with CaCO3, gypsum, and Fe(OH)3 and precipitated by neutralization at pH <5.0. By the slow neutralization and aging process with DAA (dodecylammonium?acetate??[2016-56-0]) gypsum can be separated from Fe(OH)3 by flotation. However, by a rapid neutralization in the presence of 29 mg/L DAA and <29 mg/L starch??[9005-25-8] as flocculant gypsum and Fe(OH)3 are well separated from each other by flotation and sedimentation, resp. at pH 4.8-5.1 with recoveries of 90 and 92%.
