摘　　要：采用氧压浸出工艺从艾萨炉炼铅烟尘中高效浸出锌、镉,研究了氧压浸出温度、初始硫酸浓度、氧压浸出时间、氧气压力、液固体积质量比对锌、镉浸出率的影响。结果表明,在初始硫酸浓度为40 g/L,液固体积质量比为3 mL/g,氧压浸出温度为120℃,氧压浸出时间2.0 h,氧气压力为0.6 MPa,搅拌速度为600 r/min的条件下,锌、镉浸出率分别为72.19%、96.95%。Efficient leaching of zinc and cadmium from lead smelting fume of ISASMELT Furnace has been carried out by using of oxygen pressure leaching process,it is studied the effect on zinc and cadmium leaching rate of oxygen pressure leaching temperature,initial sulfuric acid concentration,oxygen pressure leaching time,oxygen pressure and liquid-solid volume-to-mass ratio.Results show:when initial sulfuric acid concentrate is 40 g/L,the liquid-solid volume-to-mass ratio is 3 mL/g,the oxygen pressure leaching temperature is 120℃,oxygen leaching time is 2.0 h,oxygen pressure is 0.6 MPa,the rotating speed is 600 r/min,the leaching rate of zinc and cadmium separately are 72.19% and 96.95%.
