| 摘要 |
<p>The invention relates to a process for treating an effluent that contains metals, comprising: - at least one step of extraction of the chloride ions present in the effluent, in the form of metal complexes, by liquid-liquid extraction in the presence of an extraction agent, in which at least one metal taking part in the complexation reaction is present in the initial composition of said effluent or is added thereto in an amount that is at least stoichiometric relative to the amount of chloride ions, and - at least one step of extraction of the aluminium present in the raffinate resulting from the chloride ion extraction step(s).</p> |
