Inoue, Toshio published the artcileTreatment of metallurgical wastes containing heavy metals. II. Separation of lead sulfate and ferric oxide with dodecylamine acetate. With special reference to the effect of starch and arabic gum as a ferric oxide depressor, Quality Control of 2016-56-0, the publication is Sogo Shikensho Nenpo (Tokyo Daigaku Kogakubu) (1980), 191-7, database is CAplus.
PbSO4 and Fe2O3 were flotated from a solution containing no metal ions by dodecylamine acetate [2016-56-0] in the pH range 0-11 and 2-8, resp. When the same floatation tests were conducted in the solution containing 50 g ZnSO4/L, the flotation of PbSO4 was decreased to pH <3. Starch was the most effective depressor for separation of PbSO4 and Fe2O3 by flotation at pH 2.7. The Pb recovery was 90.9%.
