Froth flotation is a process used to concentrate copper sulfide ores. Ground ore is mixed with water and reagents, making copper minerals hydrophobic. Air is pumped into the mixture, creating bubbles that cling to the copper minerals and carry them to the surface. The froth, rich in copper, is skimmed off, leaving behind waste material. ...

During the entire copper smelting process, the precious metals in raw materials such as copper concentrate exist mainly with the copper and are finally enriched in anode copper. In electrolytic refining, the precious metals in the anode cannot be dissolved and therefore generate anode slime together with other insoluble elements or compounds.
