“…The supply risk of Mo is considered high, and its stabilization is a critical issue to some countries with poor resources, but the increased consumption of molybdenum, such as Korea. Korea, the first importer of Mo ores, has several molybdenum mines, for example, the Jangsu mine with a pegmatite-style deposit, the Geumseong Mine with a skarn/porphyry-style deposit, and the Geumeum mine with a veinlet-style deposit [9][10][11]. The Geumeum mine was known to have a reserve of ~2,600,000 tons.…”

This paper proposes selective leaching of molybdenum from Mo/Cu complex bulk concentrates in a 5 M NaCl solution using the electro-oxidation method. Here, the effects of several factors such as pH, pulp density, current density, and temperatures were investigated. A higher leaching yield of Mo increased with increasing pH from 5 to 9 and decreased with increasing pulp density from 1 to 10%. A rise in current density did not help enhance Mo, and the elevating temperature did not always result in a higher leaching yield. Application of ultrasonic led to higher leaching yield of Mo. Ninety-two percent of leaching yield was obtained upon leaching of Mo in 5 M NaCl at 25 °C, pulp density of 5%, and the current density of 0.292 A/g under ultrasonic irradiation with a power of 27 kW. The resultant residue mainly consisted of chalcopyrite.
