MEI''s Barry Wills: Challenges in copper flotation

Sep 10, 2011Then, the flotation must be capable to produce copper concentrates of low and high arsenic content. The second one must be treated by an alternative process. The treatment of copper ores with some degree of oxidation is other problem. In this case, the mine usually tries to send to the flotation process a material easy to treat.

Removal of Metallic Impurities from Off

The copper concentrate is often obtained by conventional flotation process, but those impurities of molybdenum, arsenic, zinc and aluminum usually exist in copper concentrates. Molybdenum, aluminum and zinc are valuable metals worthy of being recovered, but arsenic lowers the economic value of the copper concentrate when the presence content of
