Gravity Gold Ore Processing Plant Flow Sheet - Andover Cares
Ore processing at Sunrise Dam gold mine operations. The leach tails are thickened further prior to deposition at the CTD TSF. The simplified flow sheet is shown in Figure 1. The plant throughput is 466 t/h at a mill circuit utilisation of 98 per cent and annualised throughput of 4 Mt/a. Gravity recovery typically ranges from 30 to 50 per cent.

Gold cyanidation - Wikipedia
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.
