Flotation is a common mineral processing method used to produce copper concentrates from copper sulfide ores. In this method, copper sulfide minerals are concentrated in the froth while associated gangue minerals are separated as tailings. However, some amount of copper is lost to tailings during the processing; therefore, tailings can be considered
