2016-4-6 One 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.
