Rich Placer Gold Deposit - Very Fine Gold

by Ken Cunningham
(Myrtle Point Oregon)

I have come up on a very large "Sand" Placer Gold Deposit. However, it is Micron Size in every sense of the word. Black and blonde sands are the same size as the gold. I can not determine a proper way to separate the Gold from the inclusions. Classified some @120 mesh. Some gold and material comes through and some lays on top. Tried a "Blue Bowl".(Washes out) I can't seem to capture the gold content separate? This stuff was gold mined in the 1850s/60s.

Stan's response: Hi Ken, if you are planning to gold mine on a small scale, I would try a spiral concentrator wheel and experiment with all 3 settings.

If you are planning to gold mine on a large scale, I would use a gold wash plant with jigs and a large spiral concentrating system such as Oro Industries produces in Northern California.

If those methods don't work well enough and if the material is rich enough, I would try amalgamation or leaching.

If none of that works, I would look for a new deposit with coarser gold!

Similar Fine Gold Situation on Alaska Beach
by: Jason Cunningham

We have big gold bearing black sand deposits on the beach where I'm mining in Alaska, 75% of the material being magnetite.

One of the processes we are using to recover the gold that is free from other metals, is to run it down a big long wide beach box (basically ribbed vinyl matting). There is no miners moss and no riffles, just like in Nome with the exception of our electro-magnet mechanical arm for getting rid of the magnetite fast enough to be able to make a profit.

A further way to increase production of this limitless beach placer is to incorporate a rocking system on the beach box, like a rocker box.

The second system is a tumbler and mercury, which we retort after the gold is amalgamated. We also have platinum group metals in the mix, which along with all the gold, is liberated from the heavy sands after running through a home made ball mill, then again run through the tumbler with mercury.
