Heap leaching of ore or concentrate is used mainly with cyanide (recovery of gold is around 60-90 %). Situ leaching is used with chlorine too (extraction of gold may reach 75 %). Also there are pressure leaching and bacterial leaching. Chemical processing is not used for macrogold and colloidal gold.

Gangue Mineral - an overview | ScienceDirect Topics

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.
