ultrafine grinding of pyrite

Ultrafine Grinding an overview ScienceDirect Topics

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 (<20, >0.02 μm) gold mineral inclusions in the pyrite and/or arsenopyrite. By grinding to 80% passing 10 mm a significant fraction of the colloidal size (<0.5 μm) gold is also being exposed and rendered amenable
