Gold Extraction Techniques - Manhattan Gold Silver

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.

How is gold mined? - Gold-Traders (UK) Ltd

In placer mining, the gold is retrieved by metal detecting, panning, cradling, sluicing and dredging. Using gravity and water to separate the dense gold from the other materials that surround it, this is the most common gold mining category for amateur gold hunters. Hard rock mining is the process of using open pit or underground mining tunnels ...
