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. In these drums, the ore is ground to a fine slurry or,Gold extraction process,To extract gold with the CN process, you’ll first have to separate the metal items in a CPU, Motherboard and other computer parts that contain gold. Later, these scrap pieces have to be washed with a moderate strength acid solution to remove plastic, rubber, epoxy and composite. When you have the metal part clean and exposed, follow the CN process at your workshop or lab.

How is gold found and extracted from mines?
26/09/2016· Smelting is the process of melting the negative terminals (with the gold attached) in a fiery furnace, usually at a temperature of 1500 degrees Celsius. A chemical blend known as flux is added to the molten mixture to allow the gold to separate from impurities. Afterwards, the flux is drained away and the liquid gold is poured into bar-shaped moulds, and allowed to set. Once the gold bar is,Extrac-Tec | Gold recovery and mining concentration,Gold Recovery and Mineral Concentration Systems.
