The ore is first crushed into a fine powder and mixed with water to form a slurry. Chemicals called collectors are then added to the slurry, which attach to the copper minerals and create a hydrophobic surface. Next, air is injected into the mixture, causing the copper minerals to float to the surface as a froth.
