In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth For example, to separate two sulphide ores ZnS and Pbs , NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth...

The flotation process consists of several different sub-processes operating in seri These include ore slurry conditioning, followed by bubble generation, bubble collection through bubble-particle collision and attachment, and finally, bubble-particle flotation and froth separation...

Abstract-Froth flotation is widely used for concentration of base metal sulphide minerals in complex or One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a...
