Fine Gold Ore Grinding

Ultrafine Grinding - an overview ScienceDirect Topics

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.

Gold Recovery And How To Choose The Right Process ...

Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low ...
