摘要
The invention relates to a method for removing mercury impurities from metal, comprising the steps of: treating the metal surface with a liquid containing a reducing agent (for example sodium sulphite and/or sodium sulfide); and rinsing the treated metal. To enhance and/or to accelerate the mercury decontamination rate the treated metal is subjected to electrolysis. The invention also relates to plant for removing mercury impurities from metal, comprising: a treatment tank for treating the metal; means for treating the metal with liquid containing a reducing agent and with rinsing liquid; and tanks for receiving the liquid containing a reducing agent and the rinsing liquid.
