How To Build and Operate Sluice Boxes - Heckler Fabrication

For fine gold recovery the use of riffles can actually be a negative design element and most boxes specifically built for this type of gold don’t use any type of riffle system. Good examples of this box type are the ‘DFS’ (Damn Fine Sluice) and Steve Gaber’s ‘Pop-and-Son Sluice’. On the other hand boxes designed to concentrate gold particles of 16-mesh and up in size must have ...

Homemade 3 Stage Under Current Sluice Box catching Gold ...

Nearly all portable dredge sluices have Hungarian type riffles, and I wanted my homemade sluice to have them as well. The concept of the Hungarian riffle (also called the Lazy L) is that the water and gravel flow over the riffle and a little eddy sets up behind the riffle. Lighter materials continue down the box and out, but the heavier material like gold gets caught in the eddy behind the ...
