Conclusions On Gold Mineral Processing Sites Of Macalder

The occurrence of silicates in gold ores and their effect in different unit operations of gold extraction processes are analysed via a comprehensive literature review, and conclusions are drawn regarding the need for further investigation in two controversial and less researched areas, i.e. the negative impact of fine grinding on silicate.

Sep 07, 2017 A lower GSR can be tolerated if the flotation concentrate is amenable to direct cyanide leaching without the costly oxidation stage to release the gold from the sulphides. And on-site dor production avoids the off-site costs of transport and smelter charges, but usually with lower recovery (flotation recovery then oxidation-leach recovery) so a trade-off analysis is required.
