Technology for recycling valuable metal from jarosite slag
The invention discloses a technology for recycling valuable metal from jarosite slag. The technology is characterized in that a dispersing agent is added to water to be evenly stirred; then, jarosite slag and a reducing agent are added to be evenly stirred; and lime is added to be evenly stirred to obtain sediment containing ferric oxide and calcium sulfate, and liquid and solid are separated. A water repellent agent and a floating agent are added to liquid, and valuable metal is recycled. A solution obtained after the valuable metal is recycled can be used as water for dissolving jarosite slag to be recycled, and the solid sediment can be used as raw materials used in the cement production process.
