Gold is processed into it’s purest form through smelting and refining. High heat, pressure and chemicals are used to remove impurities from the gold.
A gold refinery receives the raw material (rock, gold nuggets, scrap gold etc) and re-liquefies the metal in a hot furnace, then adds various chemicals to the molten substance to separate the gold from the other metals.
A sample of the gold is used in an assay to measure the purity of the gold content, usually found to be 99.9% pure. The gold can now be used in many applications, including in electronics and jewellery making.
Pure gold is actually very soft, making it difficult to work with. The gold is usually combined with other metals to form an alloy. For example, white gold is made when you combine gold with nickel, silver or palladium. Rose gold (or pink gold) is gold combined with copper – the higher the copper content the stronger the red colour.
You can have your gold cast into bars and sell direct to a gold refinery for cash.
