Inoue, Toshio published the artcileA study on the treatment of metallurgical wastes containing heavy metals. III. Flotation of lead sulfate in the red residue of a hydrometallurgical zinc smelter, Computed Properties of 2016-56-0, the publication is Sogo Shikensho Nenpo (Tokyo Daigaku Kogakubu) (1981), 159-64, database is CAplus.
The leaching red residue from a Zn smelter contains 6-10% Pb as Pb-SO4. Zn ions are removed by washing and residual flocculant is removed by attrition grinding. The flotation pulp is heated to 35-45¡ã and treated with C12-16 amine acetate and Na hexadecyl sulfate. Flotation with combined depressants, starch, and gum arabic and 3-stage cleaning gives a concentrate containing 39-42 % Pb for a recovery of 68-70%.
Sogo Shikensho Nenpo (Tokyo Daigaku Kogakubu) published new progress about 2016-56-0. 2016-56-0 belongs to catalysis-chemistry, auxiliary class Active Esterification, name is Dodecylamineacetate, and the molecular formula is C14H31NO2, Computed Properties of 2016-56-0.
