Australian gold processing. Australia is currently the world's second largest gold producer and hosts two of the world's largest gold mines. It has a significant place in Australia's economy and gold is the third largest mineral export after iron ore and coal. It is therefore fitting to devote an issue of our journal to the technical ...Web

Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.Web
