<p>This invention relates to a method for removing thallium from a zinc- containing solution. In particular, the method relates to the purification with metallic zinc powder of a solution going to the electrolytic production of zinc. In this method, thallium is removed by means of a lead compound in the solution purification stage, either during the final purification stage or in a purification stage in which cadmium is precipitated. ® KIPO & WIPO 2007</p> |
