liberate the pyrite from the gangue allowing a low mass pyritic concentrate to be produced by a process such as flotation. However, direct leaching of the concentrate results in poor gold extractions as the cyanide lixivant is unable to contact the gold locked or included within the pyrite (Figure 1).

Gold concentrate roasting, most commonly known as dead roasting, uses Outotec's circulating fluidized bed technology. When using a dead roasting process for concentrates, the sulfides are completely transformed into oxides. The gas temperature in this type of plant is typically between 600 and 700°C.

Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines. The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component. The concentrate is then transported to smelters where it is used to produce useful metals.
Gold. In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.
Significant advances have taken place in the treatment of refractory gold ores and concentrates during the past decade. In sulfide ores, pyrite is the most common host mineral for gold. Studies by Gasparrini (1983) showed that gold occurs in pyrite as native gold or electrum in all sizes and forms. Arsenopyrite is probably the second most common host for gold and forms similar associations ...
