Sphalerite (ZnS), galena (PbS) and pyrite (FeS2) are the important metallic sulphide minerals. These three sulphide minerals are often associated with each other, and large amounts of sphalerite and pyrite are lost in the galena flotation tailings. In this study, the flotation method was employed to recover sphalerite and pyrite from a galena flotation tailing waste.

In this paper, based on the experiment on pure minerals, namely, galena, sphalerite and pyrite, it is concluded that the appropriate pH range for galena flotation is 8.5-10.5, that for sphalerite flotation is 7-10.5 and for pyrite is 2.5-6.5. For galena, sphalerite and pyrite, butyl xanthate has a better collecting performance than ammonium dibutyl dithiophosphate.

A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar.
