Abstract
The present disclosure relates to a method for removing halide from halide-containing Waelz oxide. According to the method, it is possible to effectively remove halide contained in Waelz oxide, especially insoluble fluoride such as CaF2, which are difficult to remove under atmospheric pressure conditions and present as insoluble substances. Accordingly, in the process of recovering valuable metals, an additional process for adjusting the concentration of fluorine or chlorine present in the electrolyte can be omitted, and costs can be reduced.
