Citigold Corporation has access to a modern gold extraction plant that is located away from the populated areas of Charters Towers about 10 kilometres south west of the city centre along the Gregory Highway on the historically rich Black Jack mine site. The plant is a conventional CIL (Carbon In Leach) plant with a capacity to process about ...
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
In Benguet province, a group of miners have been using the mercury-free gravity-borax method (GBM) for gold extraction for decades. This method basically requires the same equipment as the amalgamation methods. However, after the rod milling, an ore concentrate holding the heavy minerals is produced by using a launder (gold sluice) and a gold washing pan.
