The predominant function of collectors is to selectively induce hydrophobicity onto the desired mineral. Collectors are therefore concentrated at the mineral–water interface. Collectors are heteropolar molecules containing a non-polar hydrocarbon chain (hydrophobic contribution) and a polar group that interacts with the mineral surface.
