- Title
Using Mineralogy to Optimize Gold Recovery by Direct Cyanidation.
- Authors
Venter, D.; Chryssoulis, S. L.; Mulpeter, T.
- Abstract
The complete and accurate gold deportments of direct cyanide leach residues provide a clear picture of the occurrence of unrecovered gold and identify causes for poor extraction. Based on the independent measurement of each form and carrier of unleached gold, opportunities for recovery optimization can be assessed more accurately by providing meaningful targets and can help identify the means to achieve such targets. In ten of 14 leach plants surveyed, 23% of the unrecovered gold could be extracted without finer grinding. INSET: MINERALOGICAL CHARACTERIZATION.
