Alkaline Oxidative Leaching of GoldBearing Arsenopyrite Ores
of the leach residues resulted in 90 to 93 pct Au and 60 to 80 pct Ag extractions, compared with only 5 and 15 pct, respectively, without the pretreatment. The procedure was further tested by leaching a lowgrade gold ore and a bulk sulfide flotation concentrate prepared from it. Cyanidation of the leach
Modelling and simulation of gold ore leaching
Batch leaching tests were performed with the Sleeping Giant gold mine ore. Twelve tests were performed on a pre aerated and ground ore 50 passing 38 micrometers . Leaching was carried out at pH 11, at 50 solid, with a 600 ppm initial cyanide concentration and a saturated oxygen concentration maintained by constant injection of O 2.

different leaching kinetics. When gold is directly exposed to the surrounding phase it has a fast leaching kinetic. On the other hand, gold attacked through ore porosity, like in heap leaching, exhibits slow dissolution kinetics. Figure 1 shows four different classes of gold, each one having a different leaching behaviour. One can see that gold .
