Gold | Geoscience Australia
The most common natural method of concentration of gold is through the ancient action of hot fluid inside the Earth's crust. Fluids deep in the crust are heated by the Earth's internal heat. These fluids often have moved through the rocks over a large area and 'dissolved' the gold. When these fluids cooled …

Everything You Need to Know about the Gold Smelting Process
While melting entails heating the gold from solid to liquid form before forming gold bars, the smelting process is more complex and involves removing impurities from the gold using a combination of pressure, heat, and several chemicals. Like any other metal that appears on earth, there are impurities in gold that need to be removed.

How Gold Is Mined | Gold Mining Process | World Gold Council
Gold Mining Operation: 10 - 30 years. The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold.
