A Review of Recent Advances in Techniques for Separation of copper-molybdenum

There are abundant mineral resources associated with copper and molybdenum in the world, but copper sulfide ore and molybdenite have become a difficult problem for mineral separation due to their similar floatability. The conventional copper-molybdenum separation process is introduced in more detail, and the action mechanism, advantages and disadvantages of several commonly used copper-molybdenum flotation separation depressants, such as cyanide, sulfide, thioglycolic acid, and Knox reagent, are analyzed. Discuss; for several new types of copper-molybdenum separation technologies, including nitrogen-filled flotation method, flotation column flotation separation method, seawater flotation technology, oxidation flotation separation technology, potential control flotation technology and ultrasonic pretreatment technology, etc., they are introduced Research progress and analysis of its sorting mechanism. The article also analyzed the main problems existing in the current copper-molybdenum separation process, and discussed the future research directions.
