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.

Gold Extraction Process Know How Gold Is Mined My Gold
12/09/2017 The process causes heavier molten impurities to settle to the bottom, while the lighter molten gold floats above it. This happens for the same reason that oil floats on water owing to its density. Finally, the molten gold is extracted and cooled in the shape of the gold bar that we all know of. It takes 4 minutes for the gold to solidify
