对金含量较低（０～１００ｇ／ｔ）的铅阳极泥，用ＳＯ２直接从其金浸出液中还原金，回收率和纯度均较低。本文用螯合树脂吸附法富集微量金（０～４６ｍｇ／Ｌ）效果很好。吸附后溶液中金的浓度降至≤０．１ｍｇ／Ｌ，金的吸附率为９９．７％。经解吸与还原，金的直收率为９８％～９９％。此外，从铅阳极泥中回收银、锑、铋也取得较好结果 For lead anode slime with low gold content (0-100 g / t), SO2 directly reduced the gold from its gold leachate and the recoveries and the purity were low. In this paper, the use of chelating resin adsorption enrichment of trace gold (0 ~ 46mg / L) works well. The concentration of gold in the solution after adsorption decreased to ≦ 0.1 mg / L, and the adsorption rate of gold was 99.7%. After desorption and reduction, the direct gold yield of 98% to 99%. In addition, the recovery of silver, antimony and bismuth from lead anode mud also yielded better results
