NSC PRESSURE OXIDATION PROCESSING OF BULK COPPER AND MOLYBDENUM CONCENTRATES Dr. Corby G. Anderson CEng FIChemE and Mr. Caelen D. Anderson Butte, Montana USA FLOTATION AND TAILINGS LEACH FOR MINE SITE NSC POX PRODUCTION OF COPPER CATHODE AND MOLYBDENUM TRIOXIDE FLOWSHEET ABSTRACT Industrially proven NSC pressure oxidation leaching will be applied to bulk copper and molydbdenum containing concentrates for mines site production of cathode copper and molybdenum trioxide. This simplifies the process plan allowing flexibility in feedstocks and subseqent CAPEX and OPEX savings. This poster illustrates the application, the proposed mine plan and flowsheet and the economic estimate outcome s of this application.
