| Abstract: | Recovery of Sn,zinc and Pb from flue dust of zine metallurgy has been systematically studied in the paper.The optimum process parameters for extraction of Sn by dilute sulfuric acid leaching and extractions of zinc andPb by calcium chloride leaching have been investigated.Sn zinc and Pb can be effectively extracted fromflue dust by the process.The recovery rates of In,Sn,Pb and Zn are more than 82 %,98 %,97 % and 95 % respectively？The process has the advantages of simple operation art and high comprehensive recovery rates without environmental pollution. |
