Historic Gold Mine Tailings FAQ What are gold mine tailings? Tailings are a byproduct of a gold mining process that was common in the late 1800s and early 1900s. Goldbearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold.

Aug 08, 2014· One of the types of historic mining that is easiest to identify is tailing piles left behind from dredging operations. I am not talking about a modern suction dredge; rather we are talking about the huge bucketline dredges, dragline dredges, and smaller "doodlebug" dredges that were so commonly used in the rich gold bearing areas mainly during the early to mid1900s.
The tailings were deposited using a boom arm belt feed which could swing to allow clearance for the pile. Hence the serpentine effect. Gemstones, crystals, and much fine gold went on through to the tailings. The deposits are random so a detector is your best bet for searching these for gold. Of course gemstones are eyeball only.

Statements say all the gold in Nevada has been tapped but miniscule pieces still remain that advances in technology is helping people find. The idea is to go to locales where gold has already been found before; like old mine tailings. If you have dug some up in the past, use a GPS point to head over to that region.
Gold can still be found in dredge tailing, hydraulic pits, lode mines, and drywasher waste piles. Understanding how past areas were mined by the early gold miners can help you decide which areas are most likely to produce gold today. Locating these areas can be a great way to search for placer gold .
