Answer (1 of 2): Froth flotation is the process of selectively collect the hydrophobic material (water-hating) from the hydrophillic (water-loving) one.

Here potassium ethyl xanthate acts as a collector. $ce{KCN}$ and $ce{NaOH}$ depress the floatation property of $ce{ZnS}$ and $ce{FeS2}$ particles. Thus, only $ce{PbS}$ particles go into the froth. Now copper sulphate is added to the mixture which activates floating character of $ce{ZnS}$ and this time only $ce{ZnS}$ comes along with froth.
