Mining Gold Equipment - Mine For Gold

A prospector is able to sift through a lot more raw material with a sluice box than just with a gold pan. The sluice box quickly sheds the bulk of the gravel and waste ore, keeping only the gold and very dense sand that usually accompanies the gold. Sluice boxes are not the great heavy gold mining equipment that the old timers once used.
