At Sardis, alluvial gold mining dates to ~700 BC and gold is still produced today. However, owing to the small size of the gold at Sardis, it was necessary to use mercury to amalgamate the gold-bearing sluice concentrates as part of a modern economic evaluation of this ancient gold occurrence (Topkaya, 1984) . Amalgamation, which dates at least ...

Gold that is alloyed with silver (15–35 percent silver) is often called electrum. Both gold and silver amalgamate readily with mercury, a property that has long been a boon to the practice of extracting gold. When gold exists in ore in such a state that it can be extracted by simple amalgamation, it is called free-milling gold.
The first stage of processing gold ore is crushing. The gold then needs to be separated from the resultant powder. Coarse gold may be removed by gravity concentration. The powder is mixed with water, the gold sinks and the other wastes are washed away. Fine gold in crushed ore will be processed differently depending on the …
