摘　　要：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。By using SO2 to reduce gold directly from leach liquor of lead anode mud,the gold recovery and purity were very low due to the low gold content of lead anode mud (only 0～100g/t).Therefore,the chelating resin was used to concentrate trace gold(0～46mg/l) achieving nice effect.The gold concentration in the solution after adsorption reduced to ≤0.1mg/l,the adsorption rate was 99.7%,the direct recovery rate of gold was 98～99% through desorption and reduction.In addition,the recovery of Ag,Sb,Bi from lead anode mud was fruitful too.
