Thought you might be interested in this latest little number made for recovering flour gold mainly from sluice concentrates.

http://yukon-news.com/business/...r-miners-snag-lost-gold/

Randy Clarkson explains in an interview this week the traditional sluice box will generally turn 20,000 cubic metres of paydirt into one cubic metre of concentrate.

Miners use an array of methods to recover somewhere between 70 and 80 per cent of the gold from that one cubic metre, whether it be a smaller and specialized sluice, a gold wheel, shaking table....

But it’s that 20 or 30 per cent of gold that is too fine to be recovered with conventional methods, even too fine to be captured by traditional hand panning, he says.

This is very interesting and honestly I am surprised no one has gone through and done the research for this before, the limitation will mean you will need massive sized ones if you have gigantic amounts of concentrates but I guess you would need a very high production mine for that.

The PDF basically gives you everything you need to DIY one, and also gives some planes for a nice looking sluice box.
