how does a flotation mill work

Froth flotation - WikipediaBy 1904, the MacQuisten process (a surface tension based method) was developed but this would not work when slimes were present. In 1910, when the Zinc Corporation replaced its Elmore process with the Minerals Separation "air froth flotation" process at its Broken Hill plant, the primacy of the Minerals Separation over.how does a flotation mill work,Froth Flotation Process - 911 MetallurgistMar 25, 2017 . pH Modifiers (MBS , Lime) are used to intensify or reduce collector's water-repellent effect on mineral surfaces. This allows Flotation Collectors to act selectively towards certain minerals. Think of pH as the temperature of ambient air at which paint is applied to metal.
