Sluice box: an element of your gold recovery system
My buddy Pete and I are building some 8 ft wide sluices for one of my projects a couple of years ago. Panels like these are quick and economical to build.
Sluices have been the mainstay of most mining operations worldwide.
I strongly recommend using them wherever possible using P.E. Randy Clarkstons recommendations that he conducted in the Klondike placers in the late 1980's.
While sophisticated systems can and do increase recovery rates on some projects you need to keep close track of diminishing returns on your project.
I have found that the down time, and maintenance especially in primitive areas need to be addressed constantly or your overall recovery can be compromised.
