Gold is generally extracted in openpit mines at 1 to 2 ppm (parts per million) but in certain cases, ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia. Nickel, generally as laterite, is extracted via openpit down to %.
pile for either later use to fill the pit or to use in new land forms. From there the mineralised ore is removed. Explosives are used to break the ore which is then scooped up by front end loaders or electric shovels, loaded onto large trucks and taken to the processing plant. Mining continues until the pit becomes too deep, too
The sulphide ore from the Open Pit is refractory and requires a complex series of processes to extract the gold. The freemilling Mt Charlotte ore, which is easier to process, was formerly directleached after grinding but is now combined in small batches with the Fimiston sulphide process. The ore from the Fimiston Open Pit and Mt Charlotte Underground Mine is processed at KCGMs Fimiston and Gidji
Depending on the ore, we process it using the following methods: We feed ore into a series of crushers and grinding mills to reduce the size of the ore particles and expose the mineral. Water is also added, which turns the ore into a slurry.
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
