Ultra Fine Milling For The Recovery Of Refractory Gold

Ultra Fine Milling For The Recovery Of Refractory Gold

The size and location of the gold within the sulphide matrix determines to a very large degree the nature of the process required for its liberation and recovery. Submicroscopic gold is liberated by destruction of the sulphide with processes based on the use of thermal chemical or biological oxidation. If the encapsulated gold is coarser in size ranging say from 1 or 2 microns to approximately 20 microns then liberation can also be achieved by ultra fine milling

S. Ellis Kalgoorlie. Published 2003. Since early 2001 Kalgoorlie Consolidated Gold Mines KCGM has successfully operated an ultra fine grinding UFG circuit to supplement its roaster capacity for the treatment of the refractory gold flotation concentrate. A second UFG mill was installed in 2002 taking the total UFG capacity to over 20tph while grinding to 11-12 microns and achieving over 90 gold

Gold Recovery And How To Choose The Right Process

Gold Recovery And How To Choose The Right Process

Ultra-fine gold particles can be trapped within the mineral matrix even at extremely fine grind sizes. Three primary factors cause gold to be considered refractory. Each factor needs to be addressed with a different type of pre-treatment before gold can be recovered by conventional cyanidation. These factors are physical encapsulation chemical interference and preg-robbing elements.
