inorganic chemistry

Here potassium ethyl xanthate acts as a collector $\ce{KCN}$ and $\ce{NaOH}$ depress the floatation property of $\ce{ZnS}$ and $\ce{FeS2}$ particl 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...
