Refining Gold: How Does a Gold Refinery Work?

Gold Refining | PMT Refinery, Queensland, AustraliaGold 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.

PMT are the only gold refinery operating in Queensland, Australia and have been for the last 20 years. They can efficiently refine your gold, provide an assay for it’s purity and purchase it from you for between 96 and 98% of the world price.

      Hi Andrew, It depends on the amount you wish to have smelted but for less than 1.5kg we charge $88.00 inc GST to melt your scrap into a bar and provide you with an assay of the gold and silver content. Generally it would take less than two business days. Freight charges may also apply to return your bar. Thank you, Alan Richmond
