Document Type and Number:
WIPO Patent Application WO/2023/234623
Kind Code:
A1
Abstract:
The present disclosure relates to a method for removing halides from waelz oxide which comprises halides. According to the present method it is possible to effectively remove halides included in waelz oxide, particularly insoluble fluorides such as CaF2 that are difficult to remove in normal pressure conditions and are insoluble, and thus it is possible to reduce costs by reducing additional steps for adjusting the concentration of fluorine or chlorine present in an electrolyte during a valuable metal recovery process.
