Flotation Collectors Mineral Processing Metallurgy

Typically, for a primary amine, the ionization starts to foil off in the range of pH 10 or greater, thus defining the window of potential use as a collector to be less than pH 10. The major practical use of amine collectors is in the flotation of silica (quartz) gangue particles away from other materials, a process denoted as reverse flotation.
