Lead-zinc ore requires sequential flotation with galena being floated first followed by the flotation of sphalerite. In a typical industrial flow-sheet (Bulatovic 2007) the overall process is divided into two stages (lead and zinc flotation) with lead concentrate and zinc concentrate being the products. There is also a tailings stream.
