Method for eluting antimony adsorbed on chelating resin |
摘要 |
In a method for recovering antimony from the electrolyte of copper electro-refining process, the antimony is adsorbed on the chelating resin and is then eluted by acid. The eluate is then neutralized to recover antimony. In a conventional method, a large amount of acid and alkali is used. In the inventive eluting method, the antimony concentration in the acidic eluting solution is adjusted to 4 g/L or more in the first step and 3 g/L or less in the second step.
