中文摘要: 以铜阳极泥熔炼渣为原料，采用还原熔炼工艺回收渣中有价金属。探究渣型、Na2CO3用量、焦粉用量和保温时间对金属回收率的影响。结果表明，在冶炼温度1 150 ℃，渣相m(Fe)/m(SiO2)=0.72，m(CaO)/m(SiO2)=0.65，Na2CO3用量5%，焦粉用量2%，保温时间60 min的最优条件下，渣中Au、Ag、Pb、Bi的回收率分为97.15%、97.78%、91.27%和99.61%。实现了铜阳极泥熔炼渣中有价金属的综合回收。
Abstract:aluable metals in copper anode slime smelting slag were recovered by reduction smelting. Effects of slag type, Na2CO3 dosage, coke powder dosage and holding time on metal recovery were investigated. The results show that recovery rates of Au, Ag, Pb and Bi in slag are 97.15%, 97.78%, 91.27% and 99.61%, respectively under the optimum conditions including smelting temperature of 1 150 ℃, mass ratio of m(Fe)/m(SiO2)=0.72, mass ratio of m(CaO)/m(SiO2)=0.65, Na2CO3 dosage of 5%, coke powder dosage of 2%, and holding time of 60 min. Comprehensive recovery of valuable metals in copper anode slime smelting slag is realized.
