12/09/2017The process causes heavier molten impurities to settle to the bottom, while the lighter molten gold floats above it. This happens for the same reason that oil floats on water – owing to its density. Finally, the molten gold is extracted and cooled in the shape of the gold bar that we all know of. It takes 4 minutes for the gold to solidify

06/04/2016One of the earliest methods for extracting gold, salt cementation, was perfected through the Iron Age. When the Lydian Empire was standardizing the purity of the gold and silver they were using for the world's earliest coinage, this was the method they relied on. When mined, gold is commonly merged with silver as an alloy called electrum.
