Flotation of copper oxide minerals: A review

 — However, copper oxide ores tend to have the characteristics of strong surface hydrophilicity, high combination rate, fine particle size, serious mud problems, and complex mineral composition [8], [9]. Therefore, it is difficult to recover copper oxide resources efficiently by conventional copper sulfide ore separation method.
