Treating Low-Grade Mixed Copper Ore

     

Combined Flotation-Acid Leaching Process for Treating Low-Grade Mixed Copper OrThe flotation process comprises three steps. Firstly, a novel high-efficiency collector MA is used as the collector for sulfide copper ore to conduct direct flotation of sulfide copper ore. 

Subsequently, oxidized copper ore is recovered through sulfidization flotation and direct flotation respectively: the novel high-efficiency collector MA serves as the collector for sulfidization flotation, while sodium oleate is employed as the collector for direct flotation of oxidized copper ore. The flotation mixed concentrate is centrally subjected to acid leaching treatment, and the filtrate is collected after filtration.

This method improves the copper recovery rate and reduces production costs by integrating mineral processing and metallurgy. Additionally, it is simple and easy to implement.
