12" ocean dredge sluice- Nome

You will blow all your fine gold out.

That water's not too fast... Gold drops out usually in the front 25% of the dredge. We ran ours like this all the time, albeit smaller ones, but the volume to sluice size was the same. I dropped lead fishing weight in to test before, and they never made it past the midpoint of the sluice.The vibration of the dredge helps settle the gold out too.

Holy crap, I have had minnows swim up my sluce before but you my friend should be on the look out for salmon. 12 inches that if huge.

Way too much water, my friend. You want about a 10% to 20% pulp density to optimize recovery with a sluice. You need to either dewater with elutriation (by about half) ahead of the sluice or spread the pulp out over a sluice section w/expanded metal about double what you're currently running. Good luck!

nice dredge setup there

[Preciprex]

Got a question for ya. Isn't that sluice running WAY too fast? Can you recover any fine gold at all?

[AWCPRODUCTION]

it's a 12" dredge....they have much larger riffles and catch the good stuff. Dredges normally work much faster water than a stream sluice.

please do tell how???? what is the rate of settle in a either one for gold compared to horizontal water flow/volume??? is there such figures??? really would like to know??? how is this different than a trommel or should one use in in accodanance with a trommel???

[rcsupercubbuilder]

@circusboy90210 a trommel is fed by heavy equipment and is for use on dryland. a dredge is used in rivers, creeks,streams, and oceans as seen here. using a dredge with a trommel would give extremely low results in performance. that is becasue the higher you have to lift the stuff going in the nozzle it lowers suction, so dredge sluice boxes are very close to the surface of the water or actualy in the water to improve suction. the larger the dredge the more water it takes to run.
