(PDF) BULK FLOTATION OF COMPLEX COPPER ORE

The process involves a series of flotation known as the differential flotation. In the flotation of copper-zinc massive sulfide ores, flotation properties of copper and zinc are determined by the nature and composition of the ore. Copper zinc massive sulfide is even regarded as the most complex ore and consequently the most difficult to treat.

The ultimate molybdenite recovery decreased from 92% in the absence of skarn ore to 85% with 25% skarn ore and 56% with 50% skarn ore in the flotation feed. Copper flotation was affected to a much lesser extent.

A New Technique for Recovering Copper From Complex

Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing agent and butyl xanthate as a collector.
