Thallium extraction process - Metaleurop S.A.

The invention relates to a process for extracting thallium present especially in aqueous wastes of industrial origin. The process, which makes it possible to extract and recover thallium from a solution which contains it in the form of a salt of a strong inorganic acid, comprises a stage of bringing the said solution into contact with an ion exchange resin containing a thiol group.

Method for the removal of thallium - Noranda Inc.

A method for removing thallium ions from aqueous solutions uses manganese dioxide sludge produced during the electrolysis of zinc. The preferred allotropy of MnO 2 is the α-form, which selectively absorbs thallium ions with minimum interference from other elements and metal ions present in the solution, and is significantly more economical than other reagents currently used for the same purpose.
