Ultrafine Grinding - an overview | ScienceDirect Topics
Eleonore Mine is the first commercial application of the IsaMill in Canada (Deschênes and Fulton, 2013). Ultrafine grinding is applied to liberate gold finally disseminated in sulfide minerals. The pyrrhotite concentrate produced by flotation was used to determine the leaching strategy at the laboratory scale.
Ultrafine Grinding - an overview | ScienceDirect Topics
For ultrafine grinding, a choice has to be made between two grinding media using a pin mill to grind quartz. The two grinding media available have a Mohs hardness of 7 and 8 and specific gravity 2.7 and 3.0, respectively. The mean product size, P80, is required to be less than 10 μm.
