    Copper and moly are often found together as sulfides, which in solution will float or sink with the right combination of chemicals and gas bubbles (froth flotation). The sulfide ores are separated from gangue (waste) material, then from each other, by froth flotation. This separation and concentration of copper and moly is called the coppermoly
