Method and apparatus for homogenising and stabilising an iron-bearing residue |
摘要 |
<p>A method and apparatus for converting an iron-bearing residue generated in the hydrometallurgical process that contains small amounts of soluble heavy metals into stable form be means of a neutralising agent. The residue is elutriated and the elutriated residue is fed into at least one stabilation or homogenisation reactor (3) into which a neutralising agent is also routed, and the homogenous mixing together of the residue and neutralising agent takes place by means of a helix mixer (8), where the ratio of the diameter of the mixer to the diameter of the reactor is 0.75-0.99.</p> |
