The zinc hydrometallurgy technology has been popular since the beginning of the 20th century. Because of its large production scale, low energy consumption, and easy to realize mechanization and automation, it has developed rapidly. How should iron and manganese resources produced in the zinc hydrometallurgy process be used efficiently? Let me tell you something about Shaanxi turbulence electrowinning project!
The manganese ion in the zinc smelting electrolyte needs to be kept at a certain content so that the electrolysis can operate normally. If the manganese ion content is too low, the formed anode mud cannot protect the anode well, affecting the quality of zinc and increasing the consumption of anode materials. If the manganese ion content is too high, the consumption of auxiliary materials will increase, which will also increase the resistance of electrolyte and affect the reduction of electrolytic efficiency. In zinc smelting, iron ions are used to remove impurities by polymerization sedimentation under different process conditions. Under normal conditions, ferrous sulfate and manganese powder are added to supplement iron and manganese ions in the system. Through the research on the liquid containing iron ions and the electrolytic anode slime containing manganese in the zinc smelting system, the proportion of the liquid containing iron ions, anode slime and manganese powder entering the system has been studied. * The consumption of ferrous sulfate and manganese powder has been greatly reduced by making full use of the liquid containing iron ions and manganese ions in the electrolytic anode slime.
Technical innovation: Through the research on the leaching process of manganese containing electrolytic anode slime, the proportion of iron containing ionic liquid, anode slime and manganese powder entering the system is adjusted, and the consumption of ferrous sulfate and manganese powder is greatly reduced by making full use of manganese ions in iron containing ionic liquid and electrolytic anode slime.
The automatic manganese powder blanking device was developed, and the * * manganese powder blanking was continuous and stable. Research and develop the process control method of iron containing ionic liquid entering the system, * * iron containing ionic liquid enters the system uniformly.
With the continuous development of zinc hydrometallurgy technology, its output must be fully collected and utilized. Only from the perspective of environmental protection, comprehensive utilization can also contribute to our environmental protection cause. From the perspective of environmental protection and efficiency, Shaanxi Turbulent Electrodeposition Project has made the best use of everything.
