Improving gold recovery from a refractory ore via Na2SO4 .
· This paper reports our attempt to improve the gold recovery from refractory gold ore. Na 2 SO 4 is added to further optimise the O 2 enriched single stage roasting. An alkaline sulphide leaching step is also added to remove Sb. Thermodynamic analyses are used to establish possible mechanisms for the experimentally observed improvements. 2.

The Mining Process
The Mining Process. Gold at Macraes is known as 'refractory ore', which means it is ultrafine and resistant to the typical cyanide leach process. The mining process at Macraes is circular and follows a cycle of exploration, mining, processing and rehabilitation and closure. With a 30year history of development spanning fluctuating gold ...

gold processing
Such ores are referred to as refractory, and they frequently contain the sulfide minerals pyrite, pyrrhotite, or arsenopyrite. Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast goldbearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to ...

Carbon In Pulp Carbon In Leach Gold Processing Plant Diagram
Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the MerrillCrowe zinc precipitation process and the other is the adsorption of the gold onto activated carbon. Gold Recovery Process Flow Diagram
