The Recovery of Gold from a Copper-Rich Zimbabwean Gold Ore …
The global gold ore grade has been decreasing, and the mineralogy is now more diverse and complex. This has necessitated the utilization of low-grade ores previously not used. During the cyanidation process of such ores, copper cyanide complexes form that are competitively adsorbed with gold onto activated carbon. Therefore, to decrease the amount of …

Gold Extraction from a Refractory Sulfide Concentrate by
Most gold deposits occur associated with sulphides like pyrite and arsenopyrite; thus, precious metal dissolution is possible by oxidizing auriferous sulfide concentrate using simultaneous pressure oxidation and cyanidation. The effectiveness of this process of extraction can be influenced by the temperature, cyanide (NaCN) concentration, and oxygen pressure. In …

The second gave a concentrate containing $20.20 gold, 7.8% copper, and 27% insoluble, with an extraction of 64.5% of gold and 91.8% copper. The gold left in the tailing was probably in the gangue, as the extraction was poorer than usual. As a rule, the longer agitation and separation are continued, the more silicious the concentrate is.

Treatment of copper-rich gold ore by cyanide leaching, ammonia
The ongoing depletion of gold and silver-containing ore deposits demands a shift towards the processing of more complex sources. Leaching of gold or silver from these sources, which are named refractory and are typically low-grade, can be complicated due to one or more of the following effects: (1) kinetic or thermodynamic impediments on cyanide diffusion or on the …

Biogenic sulphide for cyanide recycle and copper recovery in gold
Copper–gold ore processing (higher copper values than gold values) generally involves flotation and smelting. In the latter case, gold credits are obtained from the smelting of the copper concentrate, and if gold reports to the flotation tailings, they may also require cyanidation. A notable and relevant exception to this generalization is ...
