S.L. Chryssoulis, J. McMullen, in Gold Ore Processing (Second Edition), 2016 3.3.8 Response to Ultrafine Grinding CIL. UFG of pyrite concentrates for subsequent leaching is used in ores, where refractoriness to direct cyanidation arises from fine to ultrafine (0.02 μm) gold mineral inclusions in the pyrite and/or arsenopyrite.By grinding to 80% passing 10 mm a significant fraction of ...

Wet ultrafine grinding has been increasingly used for production of ultrafine powders in various industries. It has been known that slurry rheology significantly influences the grindability of industrial minerals in wet ultrafine grinding. This review represents some previous work with respect to slurry rheology in ultrafine grinding.
