Gold, except the 24K gold, comes with copper. So, 18K or 22K gold is not pure. If you go for the traditional process, then removing copper from gold can be a very challenging thing. However, with a modern induction gold melting machine, this can be done quite easily. To remove copper, you may need to use around 50 percent nitric acid.

Copper Slag

Copper Slag is by-product or waste stream from the production of copper. The smelting process produces a glass like substance that will settle on the top of the melting copper and is basically the non-copper impurities being separated. The slag is then skimmed off the melted copper and delivered to a "slag heap" or slag dump where it is left to cool.
