    Energy Use of Fine Grinding in Mineral Processing ...

    Dec 18, 2013  In fine grinding, a material with an F80 of less than 100 μm is comminuted to a P80 of 7 to 30 μm.(P80s of 2 μm are at least claimed by equipment manufacturers.)The feed is typically a flotation concentrate, which is reground to liberate fine particles of the value mineral.
