Heap leaching a stack of gold | MiningFeeds

High-grade ores and ores not amenable to cyanide leaching at coarse particle sizes require further processing to recover the  gold  values. These processing methods can include further grinding, concentration, pressure oxidation, and roasting, which is used to treat these ores to expose the gold particles prior to cyanidation.
