29/02/2016 · The first one comprises several steps: crushing and grinding operations oriented to liberate gold particles so that they can be leached. The comminution product must be 8090% passing 75 µm. Normally, the processes is employed when the gold content is ranging from 5 to 15 g/t.
G. Deschênes, in Gold Ore Processing (Second Edition), 2016 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.
Comminution is the process where ore particles are liberated from gangue material through progressive size reduction in the form of crushing, grinding, cutting or vibrating. The costs associated with power supply, grinding media, and liners used in comminution circuits almost always represent the single largest cost in gold extraction processes (Mosher, 2005).
The lowest cost gold is normally produced by open pit mining with minimal crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 9599% by grinding to fairly fine .
