Fine gold recovery study. Interesting !

I stumbled across an article, talking about a fellow using a rocker box using a copper plate and potassium to increase his take. Completely over my head
then i found this pdf on the study of fine gold recovery around the world. Heres the link.

Interesting article.....Long but still interesting.
I use a Cleangold sluice for my beach mining in Oregon ... It works very well on the fine beach gold we get her that ranges from -60 to +350 mesh.



I also use a Goldcube for cleanup...

I see my Model 5 fluid bed listed as Graffe's E tank or the Keene Hydromatic Jig. Looks like the mods I'd like to make were already anticipated to some extent. From the article, I should be hitting ~93% at 400#.
