Sulfide sulfur oxidation through the autoclave is typically of the order of 90—92%. Residual S exiting the autoclave is targeted at less than 0.2%. Values greater than 0.25% S" typically result in poorer gold recoveries in the C1L circuit. Free-acid levels in the autoclave discharge are a function of S2 and CO2- in the autoclave feed, but ...

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 gravel-like material then enters rotating drums filled with steel balls.
