Ultrafine Grinding for Direct Cyanidation Many refractory gold bearing ores contain gold in close association with sulphide minerals, such as pyrite and arsenopyrite. Refractory gold may be present in several forms, ranging from fine free gold housed on boundaries between mineral grains, to gold that is in solid solution with the sulphide matrix.
G. Deschênes, in Gold Ore Processing (Second Edition), 2016. 4.4 Ultrafine Pyrrhotite Concentrate. Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002).The gold sulfide concentrate is grind with an IsaMill to a P 80 of 10–12 μm.
