METHOD OF RECOVERING HIGH-PURITY INDIUM USING COMPLEX FUSED-SALT ELECTROLYTIC REFINING PROCESS

摘要

The present invention relates to a method of recovering high-purity indium using a complex fused-salt electrolytic refining process, which is configured to produce an indium monochloride electrolyte with fused-salt used as an electrolyte, then insert low-purity indium to a the complex fused-salt electrolyte produced by inserting metallic chloride into the indium monochloride electrolyte, and to recover high-purity indium by an electrolytic refining process. The present invention establishes a method of removing impurities of low-purity indium metal and recovering high-purity indium metal by using a complex fused-salt electrolytic refining process, thus having an effect of acquiring optimal generation efficiency and optimal refining efficiency when performing the electrolytic refining process by using the method thereof.;COPYRIGHT KIPO 2017
