Galena (PbS) is the most important lead-bearing mineral and a major source of lead metal worldwide. As a sulfide mineral, galena often coexists with other valuable sulfides such as chalcopyrite (CuFeS 2) and sphalerite (ZnS), as well as the gangue mineral pyrite (FeS 2) [1].The separation of galena from these other minerals is accomplished through froth flotation [2], …
