how to separate gold from sand with machine

History of gold - Only 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.

How I built a recirculating sluice box for gold prospecting

To do a cleanup, I first pick out any large pieces of gold that are stuck behind the first couple of riffles (see photo above). Next I unscrew the two hinge bolts that hold the sluice in the cradle and disconnect the water hose. Then I put the sluice into a 5-gallon bucket and pour water down it to wash the concentrates into the bucket.
