Consequently, complexities of ore mineralogy pose a lot of mineral processing challenges (Feng and Deventer, 2010). Gold can be found in complex sulfide minerals in particular, pyrite and arsenopyrite (Asamoah et al, 2018). In refractory gold ores, the gold is highly encapsulated in the sulfide matrix and pre-treatment is an important
The gold is particulate within arsenopyrite grains. The RGO ore is a complex refractory gold ore. Whilst flotation and concentrate roasting, pressure oxidation (POX), and bacterial leaching (BIOX) were all studied the environmental regulators would not agree to chemically changing the arsenopyrite containing the gold.
EMMC started mining the property in 1936 with a 100-tpd straight cyanidization mill capacity, which increased to 200 tpd just prior to the outbreak of World War II. Operations ceased soon after. MMC took over in early the 1970's, producing, until 1982, a total of 82,683 tonnes of ore averaging 7.46 g/t gold.
