| Abstract: |
| With the increasing depletion of easy-to-elect copper-lead-zinc sulfide ore resources, the development and utilization of a large number of difficult-to-elect oxide ore resources is being paid more and more attention. Sulfide flotation is the main method for oxide ore enrichment and recovery, but the good or bad sulfide effect directly affects the flotation index. In this paper, we analyze the surface characteristics of three typical copper-lead-zinc oxide minerals, namely malachite, cerussite and smithsonite, and explain the surface sulfidation mechanism of the three typical oxide ores, and summarize the enhanced sulfidation methods and research progress of the oxide ores. |
