Selective Leaching of Molybdenum from Bulk Concentrate by Electro-Oxidation
Metals, 2021 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 ...

Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Acta Geologica Sinica - English Edition, EarlyView.The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo

Study on Process Mineralogy and Mineral Processing Technology of A Low Grade Copper-Molybdenum Ore
Kuangchan zonghe liyong, 2023 A copper-molybdenum ore in Qinghai contains 0.084% Mo and 0.067% Cu. Process mineralogical study shows that molybdenum in the ore mainly exists in the form of molybdenite, while copper in the form of chalcopyrite, chalcocite and bornite.

Engineering Reports, Volume 8, Issue 5, May 2026.Copper sulfide concentrate leaching in sulfate–chloride media was significantly enhanced by chloride ions and stabilized hydrogen peroxide. Ethylene glycol suppressed oxidant decomposition at high temperature, increasing copper recovery to 75.2% and overcoming chalcopyrite passivation through a surface‐reaction‐controlled mechanism.
