The tailings pile here has plenty of stuff to pick through. We found a couple of stray clear quartz crystals, but mostly white or orange quartz with minerals such as the shiney black galena mixed in. The chalopyrite was hard to find, but pretty with it''s shimmery blue/green pieces.

Man-Made Gold Indicators

 · The tailing piles left behind are very evident today; large, uniform piles of rocks and gravel, often for many miles along the valley floor. Dredge tailing are very attractive to prospectors using metal detectors. They still hold good potential for gold, particularly large gold in quartz specimens that were rejected by the classifier of the ...

Cyanide Tailing Piles

 · Also look for "High Grade Ore". Or just look at the tailings to spy free gold. I have a recent post where I ran across an old hard rock mine with quartz tailings and there was some obvious gold visible. Later we crushed pieces and there was gold inside. (and a good amount of it) You need a good detector for the really small stuff.

Tips from the Tailing Pile

Harvesting Fallen Gold | MW MINING & INSPECTIONS, INC.

The real money here is in fine gold, but these old mining types of operations lost surprising amounts of large gold also, especially if the gold contained or is mostly composed of quartz or iron ores. Large gold-quartz /iron specimens just rolled through these systems along with the other rock and landed in the tailing piles.

The overflow from the tailings thickener is sent to the water reclaim pond and then recycled back into the process.

More on Tailing Piles and Old Workings

 · Specimen gold or gold still in the host rock comes in many forms and I have found some very impressive crystalline gold on quartz over the years in the old throw away piles or dumps. In the old days ore was sorted by hand and if you couldn''t see gold you threw it away, but often there was gold within the rock that was not visible.

Revegetation of Gold Mine Tailings (Active mine

Water from the slurry accumulates on the top of the tailings, from where it is recycled through the processing plant.
