    Eight Factors Affecting The Flotation Process

    In general when the grinding fineness is less than 0.01mm the flotation index decreases significantly. When the grinding fineness is less than 2~5μm the useful minerals and gangue minerals can hardly be separated. Therefore selecting the appropriate grinding fineness has a decisive significance to the effect of the flotation process.

    Energy Use Of Fine Grinding In Mineral Processing

    Dec 18 2013 Fine grinding to P80 sizes as low as 7 μm is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding it can still account for a substantial part of a mills energy budget.
