It is a for the concentration of sulphide ores.In this process we use powderd suplhide ores and to it we add froth stabalizers(aniline) and collector(pine oil or xanthates).The principle behind this process is the collectors increases the non wetability factor of ores and gaunge particles get wet by water. A paddle connected to it draws aor in the froth and aggitates the mixture such that the froth comes up and skimmed out whereas gaunge particles settles down in the water. You can also give example which is given in the textbook last paragraph of froth flotation topic(ZnS and PbS). :)
