    Flotation Reagents Collectors ArrMaz

    Collectors, some of the most important flotation reagents used in the flotation process, are used to modify the surface properties of minerals. A collector is a chemical that selectively binds to the surface of target minerals and imparts hydrophobicity to those mineral particles, a necessary condition for air bubble attachment.
