Bear,
Buy or make your own sluice, recycling the water with 12V bilge pump. Add dishwasher liquid to the water and you will be left with the fines and some iron stone. A magnet removes most of this.
Good luck.

I know I will probably get plenty of ridicule from some, but mercury is the easiest way.
I use a little rock tumbler that you can get for a couple hundred. Stick your material in it and one ounce of mercury tumble for 1 hour then get your mercury out and retort.
Quick and easy way to make sure your getting all of it.
If you got lots of material just get a bigger tumbler, I'm making one out of a beer keg at the moment with rods in it for fine grinding.

What about a gold cube everyone in kal is raving about them.

How much dirt do have to be processed,few weeks times I should have all my gear set up be able to do it over a couple of beers.

its about 5 kilos of real fine stuff its just shot with fine gold and floaty gold too

Gold wheel will not do any good.

I have seen the gold that Bear has and its that fine it would float away if u let the wind at it.

I have used the gold wheel and the Cube and in this situation u would loose most of the gold--its ultra fine.

I soon will have a gold table and I reckon the stuff will simply float away in any direction so looks like mercury will be the winner in this case.

will wait to hear from Vangold once u r set up maybe....

Yep, It sounds like mercury is the go if the stuff is that fine. Only thing I'd say is that if it's an alluvial specimen, make sure it has had a good grinding in a small mill/dolly pot. The mercury doesn't like sticking to the alluvial as much as underground ore. Maybe there's a solution someone knows about that you could soak it in prior to fixing with mercury?
cheers

I run mine in the tumbler with sodium hydroxide (high strength oven cleaner) first and also a handful of 1" stainless bearings. The sodium hydroxide neutralizes any sulphides and helps the merc attach to the gold better. (So I'm told, but it seems to work).
Run it like this then rinse the water out , add new water and mercury.
Oh and use distilled water with the sodium hydroxide.
If your down near Meeka anytime I can do it for you and show you how it works.

every thing has been dollied down to powder but the gold  is so fine ,i dont have access to mercury ,,im going to try the auto pan with a small amount see how i go  just be a shame to loose 50% or more of the material as its full of the fine stuff
keep you guys posted ,,,da bear
 

Save the overflow from your pan and keep running it through. Don't forget the "rinse aid."

Da Bear got a retort and can get a little merc just gave some away a week or so ago,Don't no how to pm you so if you can try catch up if you can find away.
Cheers vangold
