Despite flotation can separate copper and zinc from gangue minerals, the deep separation between them is a long-term challenge in mining field. Firstly, chalcopyrite and sphalerite may coexist closely in copper-zinc mixed ores, it is difficult to completely separate them by grinding technology (Leppinen et al., 1998).

In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those low-graded ores with complex embedded features. Therefore, it's a significant step for separating lead-zinc, copper-zinc, copper-lead to choose right flotation reagents.

How to separate Zinc and Copper? Copper is a very versatile material that can be used in many different ways. The process of separating copper from other metals and materials is straightforward, but requires some knowledge of the field to do it correctly. In many cases, the best way to separate copper is by heating it up past its melting point.
