More recently, in both hard rock and alluvial gold mining within NSW." About gold recovery, Ian says: "With gold, the Wave Table can be used in the smallest to the largest gold mine. Wave Tables can be used for full scale production purposes, or simply as a clean-up/concentration device in the gold room.
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.

The town was set up on a piece of land that was previously a farm called Randjieslaagte.
When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
