ELECTROLYTIC COPPER REFINING DEVICE, AND ELECTROLYTIC COPPER REFINING METHOD USING SAME

摘要

Disclosed are an electrolytic copper refining device, and an electrolytic copper refining method using the same, which are capable of producing high-quality electrolytic copper at low manufacturing cost. The electrolytic copper refining device (10) is provided with a copper electrolysis tank (17), an electrolyte supply unit (11) for supplying an electrolyte to the electrolysis tank (17), an additive tank (12) for supplying an additive containing thiourea and hydrochloric acid to the electrolyte supply unit (11), and a gelatin solution tank (13) for continuously supplying to the electrolyte supply unit (11) an aqueous solution of gelatin produced by continuously dissolving continuously supplied gelatin.
