Gold Extraction & Recovery Processes

2016-2-29 · Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation.

Extracting Gold | HowStuffWorks

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.
