202561· Copper sulfides and certain oxidized ores are still mainly processed by flotation, which takes advantage of the difference in physicochemical surface qualities of minerals [6]. However, the presence of clays and iron oxides in oxidized ore deposits can significantly reduce flotation efficiency and complicate the concentration process.
