History of gold

The Romans mined gold extensively throughout their empire, and advanced the science of gold-mining considerably. They diverted streams of water to mine hydraulically, and built sluices and the first 'long toms.' They mined underground, also, and introduced water-wheels and the 'roasting' of gold-bearing ores to separate the gold from rock.
