Title:
ELECTROCHEMICAL METALLURGY METHOD FOR EXTRACTING METAL AND SULFUR FROM METAL SULFIDE
Document Type and Number:
WIPO Patent Application WO/2024/045447
Kind Code:
A1
Abstract:
An electrochemical metallurgy method for extracting a metal and sulfur from a metal sulfide, relating to the technical field of metallurgical and chemical industry. The method comprises: preparing a metal sulfide into an electrode, i.e., a metal sulfide electrode, and adjusting the components and mechanical properties of the metal sulfide in the preparation process; and taking the metal sulfide electrode as an anode, and inserting the anode and a cathode into an electrolyte at an interval to form an electrode array for electrolysis. The sulfur element in the metal sulfide is oxidized and adsorbed onto the anode in the form of elemental sulfur, and metal ions enter the electrolyte and undergo a reduction reaction on the surface of the cathode to generate a metal element. The cathode is titanium, copper, stainless steel, lead, zinc, aluminum or graphite. The metal sulfide electrode is placed in the electrolyte for electrolysis to obtain a cathode metal and anode sulfur, so as to realize extraction of metal and sulfur.
