Why is there gold on top of the ground in Australia?
Source: 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.

The conventional treatment of copper–gold concentrates involves smelting, converting and electro-refining to produce a copper-cathode product. Sulfur in the copper concentrates is oxidized to sulfur dioxide during smelting and converting and is normally used to make by-product sulfuric acid.
What happens when copper is mixed with gold?
When copper (which is reddish in color) is combined with gold, the end result is rose gold, and the depth of the color will depend on how much copper has been added to the gold.
