I'm curious if a regular medical centrifuge might work. Maybe one of the 10k rpm ultrafuges.
And would the material need to be wet?
Heaven knows the density and specific gravity of gold is far higher than black sands.

I think somewhere in my wanderings I saw one invention, but it might not be hard to rig something else.
Medical equipment (used) is often available on ebay.
Cheers!

Mary,
What about an old fashioned hand cranked cream separator? Haven't seen one for 40 + years but maybe they are still around somewhere.

Lol. I don't think that would generate enough g-force.

A centrifuge could be made with a DC motor which would allow a good degree of control of the speed. It might not be necessary to attain the speeds of a medical centrifuge, but enough spin to provide separation might be accomplished at 5000 rpm or lower. The only caution is when building something like this, care has to be taken that the thing is perfectly balanced to prevent the thing from vibrating/wobbling out of control.

Yah. Balance is pretty much mandatory.
Medical centrifuges at work are generally run at around 3,000 to 4,000 rpm depending on specimen type. But some are programmable to run faster.
An older used one mighy be adapted for use this way, especially if the sample holders are metal.
Cheers!

I found the answer to processing out your micron gold, no chemicals, no mercury, and basically no talent needed. The device runs water and you add your cons classified down to 20 mesh. I can't tell you how it works but it separates your gold from your cons through different valves and then you collect the gold. Go look them up, the device is incredible, www.goldstrikemicrongold.com , 970-712-4176.
