Advances in the Cyanidation of Gold. 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 1012 μm.

Finally, according to the results, the capability of the SVR model to estimate the mining capital cost in a wide range of mining capacity is proved. So, as a whole, with a view of evaluation results, the SVR model can be used as a reliable model for estimating of the mining CAPEX. 4. Results and discussion.

Due to their significantly higher grades, refractory ores yield costs per ounce that are frequently lower than the average costs for conventional ores. Millhead grades of refractory deposits can be 86 percent higher; as a consequence, the operational costs per ounce of gold produced are approximately 19 percent lower in the case of refractory ...

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

Potential cost savings measures. This study has found that in general the relative Mining and Milling costs of a given operation do not significantly differ, and generally fall within the range of 43:43:14 to 45:45:10 (Mine:Mill:G A). In addition, G A costs were found to be consistently lower than both Milling and Mining costs.
