内容記述 | In recent years a number of methods were proposed for the treatment of complex sulfide ores. One of these studies was carried out in U.S.S.R. A study was made on the treatment of sulfide zinc ores and concentrates containing copper, lead and other metals by the sulfatization method. The study was subsequently followed by a research group at the Research Institute of Mineral Dressing and Metallurgy, Tohoku University, who developed the "Selective Sulfatization-Flotation Process" for the treatment of complex sulfide ores called "Kuroko" (Black Ore) produced abundantly in the Tohoku districts. In the present paper is described the applicability of the sulfatization process for the recovery of zinc from the mixed concentrate produced in the flotation process. It is shown that lead sulfate in the sulfatization residue could be conveniently concentrated further by differential flotation with sodium silicate and sulfuric acid to depress lead sulfate present in appreciable amount in pyrite. In the sulfatization test, the mixed concentrate was treated with about 2.5 times the stoichiometric amount of 60vol% H_2SO_4 for 1 hr at 160° to 170℃. The summary of results of the series of tests on the mixed concentrate shows that the sulfatization process can be applied in the treatment of the mixed concentrate with reasonable recoveries of zinc about 91% in solution and that the lead sulfate concentrate containing 63.3% Pb and the pyrite concentrate containing 32.8% Fe can be recovered. | |||||
