SEPARATING METHOD OF COPPER AND MOLYBDENUM

摘要

PROBLEM TO BE SOLVED: To provide a method which separates and recovers copper and molybdenum safely at low costs from a sulfide mineral containing copper and molybdenum.SOLUTION: A separation method of copper and molybdenum comprises conducting a pretreatment of electrifying between a sulfide mineral containing copper and molybdenum as a working electrode and a counter electrode, preferably cleaning the electrified sulfur mineral and then subjecting to floatation. The electrification is preferably conducted by applying a specified voltage to between a working electrode immersed in a slurry containing the sulfide mineral and the counter electrode. In so doing, the working electrode is arranged at such a position as for the working electrode to come in contact with the sulfide mineral in the slurry, and the counter electrode is arranged at such a position as for the counter electrode not to come in contact with the sulfide mineral in the slurry.
