6” x 44” Mini Power Sluice Flow Question

[audioverture]

Hi all!

I’m new to the forum and new to gold prospecting, however, I’ve been prospecting fossils for several years now… With that said, I apologize in advance for my newbie questions.

I am working on building a mini mobile wash plant for wet classifying fossils and sluicing gold. I just ordered an Adventures In Gold Prospecting (AIGP) 6” x 44” Mini Power Sluice outfitted with Dream Mat and I intend to mount everything in the bed of a Gorilla Cart (think big off-road wagon)

My main question is around flow rate for my 6” x 44” AIGP Mini Power Sluice.

Im looking at using an 18V battery powered Ryobi 600 GPH transfer pump paired with several 9AH batteries for extended run times. I like this solution because the battery attaches directly to the pump (which will be mounted in the cart) and mitigates any loose wires. Additionally, the pump has a variable 3 speed flow control which may prove convenient while classifying. With that said, I’m concerned 600 GPH is not enough flow rate to be effective while running material through the sluice.

I should add that I plan to classify down to 1/8 (or possibly as low as 1/12) as I’m always looking for fossils as I process material.

Is 600 GPH enough flow for a 6” x 44” sluice? If not, can anyone point me towards a self-contained battery powered (non bilge style) pump solution in the 1000 - 1200 GPH range?

Thanks!

I always use a 1100 GPH, with a water ajustment so i can control the water, If i need more i got it or less same thing.

Maybe use two pumps. Have six levels of adjustment. Use a sweep plumbing T to combine them.

Angle of the dangle , make slope the sluice more adjustable. With the flow rate choices you will have an unlimited range of flow rates.

As long as you get an back eddy over your riffles you are fine for water flow. Water flow and angle all come into play. If you classify to 1/8 . That is plenty I do 1/4 inch and the fines stick. I run a sluce in the water or a recycler on my driveway.

Always have enough flow and control with a ball valve.

Setting up in a stream or river is challenging. Trying to get the right angle and flow. I always classified and brought back pales of concentrates and did in a controlled environment.

Now that we had flooding I will classify a couple of pails and run the new material. Should be interesting. Never now. Everything changes all the time. You should catch most in the upper part of sluice or recycler . Some use carpet and some use miners moss. The rib on top will hold the most. Don't push the water to hard but you need to see the overburden run off . If you have anything it will stick. Do a clean up after two or three classified pails. If you want you can put a bucket on the bottom but never found much. It was always on top. Best of luck.
