Summary:The flotation of sulphide minerals and their modulation has been a subject of investigation for many years. The influence of pH, Dp, Db and xanthate concentration on the sulfide minerals floatability of is well known and it is usually used as one of the flotation control parameters. In this study, we propose to make a theoretical and experimental study concerning the use of xanthate in the sulfides flotation processes (PbS-ZnS-FeS2). Sphalerite (Dp= 0,4443mm, Db=0,1530mm) floted in pH range from 7-10.5 but galena (Dp= 0,3705mm, Db=0.2000 mm) floted better only from pH 8 to 9.5.
