Abstract

This article provides an electrolytic recovery apparatus for electrolytically recovering antimony from an antimony-containing solution, the apparatus comprising an electrolytic cell configured to store the solution; at least one cathode disposed inside the electrolytic cell; at least one anode disposed inside the electrolytic cell; and at least one diaphragm configured to separate a cathode-side region including at least one cathode from an anode-side region including at least one anode; and an electrolytic recovery method for antimony comprising: (A) leaching an antimony-containing raw material in a leaching solution to produce an antimony-containing leachate; and (B) electrodepositing antimony by introducing the leachate into the electrolytic recovery apparatus described above.
