Embodiment Construction
[0022] A method for cleaning and recovering iron in a zinc hydrometallurgy process of the present invention, comprising:
[0023] In the iron-containing zinc sulfate solution, add complexing agent, chelating agent, jarosite seed crystals, ammonium carbonate and green neutralizer to sink vitriol, liquid-solid separation to obtain jarosite precipitation and zinc sulfate solution, jarosite precipitation through fast Burn to get nano iron sulfate. The raw material formula of sinking alum is shown in Table 1.
[0024]
[0025] In Example 1-Example 12 of the present invention, the mass content of the valuable metal zinc in the jarosite slag is less than 0.5%, and the content of indium and silver is less than 5g / t.
