6. Flotation • The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral. The flotation process collects the sulfur-bearing portions of the ore, which also contains the valuable metal. • First, the finely crushed ore is diluted with water and then poured into a tank called a flotation cell.
