摘　　要：对某铜厂的竖炉烟灰进行酸浸处理,当烟灰50 g,液固比4:1,温度60℃,反应时间1 h,硫酸用量25 g,双氧水用量6.9 g,在此最佳浸出工艺条件下,锌的浸出率可达90.02%,铜的浸出率可达93.99%。其中,部分锌和铜以硫化物形式存在,造成锌、铜的浸出率难以进一步提高,需采用其他工艺对其进行处理。Shaft furnace soot are processed by hydrometallurgy process. When the amount of soot is 50 g, liquid-solid ratio is 4：1, temperature is 60℃, reaction time is 1 h, the amount of sulfuric acid is 25 g, the amount of hydrogen peroxide is 6.9 g,leaching rate of zinc can reach 90.02%, leaching rate of copper can reach 93.99%. As some of zinc and copper are existed in the form of sulfide, the leaching rate of zinc and copper is difficult to further improve, so other technology is necessary.
