【摘要】 采用蒸馏—臭氧氧化—稀硫酸浸出工艺路线处理氧压浸锌的浮选硫尾矿，主要为蒸馏法回收单质硫，臭氧氧化—稀硫酸浸出浮选硫尾矿回收其中有价元素。在温度400℃、保温时间0.5 h、载气流量400 mL/min条件下，浮选硫尾矿中硫元素的回收率可达到92%以上。臭氧对硫尾矿中Fe、Cu、As、Zn等元素的浸出具有很好的促进效果。在温度80℃、时间2 h、液固比6、氧气流量400 mL/min、硫酸浓度1.6 mol/L、搅拌速度400 r/min的条件下，Fe、Cu、As、Zn的浸出率分别可达到73.08%、90.97%、89.69%、99.03%。更多还原

【Abstract】 The process of distillation, ozone oxidation, sulfuric acid leaching was put forward to treat flotation sulfur tailings from oxygen pressure zinc leaching.The main treatment methods are distillation to recover elemental sulfur, ozone oxidation-dilute sulfuric acid leaching to recover valuable elements from flotation sulfur tailings.The recovery rate of sulfur element in flotation tailings can reach 92% above under the conditions including temperature of 400 ℃,distillation time of 0.5 h, and carrier gas flow rate of 400 mL/min.Ozone can promote the leaching of Fe, Cu, As, Zn and other elements in sulfur tailings.The leaching rate of Fe, Cu, As and Zn is 73.08%,90.97%,89.69% and 99.03% respectively under the conditions including temperature of 80 ℃,time of 2 h, L/S=6,oxygen flow of 400 mL/min, sulfuric acid concentration of 1.6 mol/L,and stirring speed of 400 r/min.更多还原
