Letter 20033
Recovery of fine floating gold
1 2
April 6, 2008
I found this site while looking for a safer method of recovering
gold from my fines I've collected as a weekend prospector. I was
hoping to find some method, such as electrolysis that did not use
toxic, dangerous chemicals such as Aqua Regia or Cyanide.
I read through quite a few pages on Letter
18889 which is dedicated to recovering gold from Electronics but
mostly it seems to involve dissolving the gold in chemicals. Has
anyone out there used or heard of using electrolysis to treat their
fines?

Don L>>>>>>>>> you are
looking for a fine gold recovery system ??
Buy you a 8 inch piece sch. 40 ,of pvc pipe and a glue on cap.
Drill the cap and screw a water valve into it, this is so that a hose
pipe can screw onto the valve. Buy some ribbed rubber matting to bed
the full half 8 inch pipe. from the cap move down about 12 inches and
cut the pipe in half long ways. Find a tripod , like the one's used
in surveying,drill a hole for a and install a carriage bolt in the
pipe in the middle. use a wing nut to mount the pipe to the tripod.
You can adjust the tripod to most any height or angle. You can run a
hose pipe from the dredge to the pipe and the valve will adjust your
flow. If you adjust the angle right you WILL recover all gold no
matter how small. The 8 inch pipe gives you a good wide bed for gold
to hangup. One person can run the pipe while the dredge is being
used. You will love this fine gold recovery system. This is all I
ever use with my 3 inch dredge.

I would like to know how long the 8" p.v.c. pipe should be to
recover the fine gold you talked about.

I agree with the person that suggested separation. Get a button up
shirt that you no longer wear, use a 5 gallon bucket and cover the
opening with the shirt and tie the shirt around the edge creating
what looks like a drum. Now put your fist into the shirt slowly to
create a funnel inside the bucket. Make sure the t-shirt will not
cave in or you will lose all the gold and have to start over. Make
sure you drill holes in the sides of the bucket so that the water
will drain out when it starts to fill up. You have just create a big
sieve. Stir up the floating gold and pour it into the sieve. When you
are done just bunch it up and dry it. Save it until you are ready to
process it into a nugget. Do not attempt to refine the gold unless
you have experience, I've done it with proper supervision and
coaching. What you have in the t-shirt is a mixture of all kinds of
material not just gold, do not go and burn it without the proper
setup. Make sure you check the drainage water from the sieve to make
sure there are no holes and the shirt is catching what your going
for. Have fun. Use a battery operated water pump so that you can just
stir the gold up and take down a beer while everything is running.

Use a large coffee filter or you can buy large sheets of material
that they use for tea bags on the net.
That will filter the floaters out of your water and also using a fine
miners moss or outdoor carpet in your box will pick up most of the
fine dust.
I use to just tie a black bandana to the top of a bucket and pour my
recirculated water through it at the end of the day and it worked
pretty well.

I recently learned of a fella in Colorado who has discovered a
safe way of gold recovery and they have been working on refining the
process since April 2008. Search "Amalgamite". Very interesting. I
have yet to try it. Came by here in search of what electronic parts
might be worthy of salvage. Thank you.

Take a potato, cut it in half. Dig out a dime-size hole in one
half of the spud, put your dime-size blob of mercury in the hollow in
the spud. Wrap spud in tinfoil. Bake spud under coals, downwind (
just in case).
Open spud, collect gold. Put baked spud in your gold pan and pan out
the mercury.
Do not eat the spud !

Wallace S.,
I sure would like a much more detailed description of the 8 inch pipe
fine gold recovery devise.
Thanks

Another method using mercury is to let the mercury pick
up the fine gold in your pan, then pour the nickel size drop
of murcury amalgum into a small depression created in an old
t-shirt. Squeeze the mercury almagum through the t-shirt and
collect your now cleaned murcury in a glass or pyrex
container. Cut the dirty brown spot out of the t-shirt as
this is now your fine flour gold adhering to the
cotton t-shirt material. You can burn out the t-shirt
material to make your gold button or even use nitric acid
solution to dissolve the cotton material and leave
outside
in well vented area to evaporate leaving just the fine
gold.

I haven't seen anything here that will collect enough
gold to cover the head of a pin.
Float gold cannot recovered by any of the above. If you want
to recover float gold you need very fine mesh bags (can be
found on the Internet under water filtering). You pump water
thru the bags for several hours. Not all water will have
gold. Only the top 2 to 3 inches and must be below a
waterfall or behind a dredge.

Floating gold can be settled by breaking the surface
tension with a surfactant "jet dry" comes to mind. Back in
my youth we used to play with a Shaklee product called
"Basic H" it was a wetting agent that would make water
wetter and break surface tension. Most of the agents I can
think of would work if you could drop small amounts in your
sluce box as you run.
Good luck and hope you always see color in your pan!
