Recirculating sluice

[Dieseltechjon]

Now I just learned something there. Going to have to test this out using a couple glasses of water.

Not sure if you have ever heard of P&G water purification powder but it will basically drop out all the heavies and give you clean drinking water. I don't know how practical it would be in the field but if you watch the video on how well it works you might be able to double the amount of water you take out by cleaning it. It's actually incredible how well it works.

Eh, I’m not into putting stuff in the water regardless if it harmless. The measurable loss from muddy water on a micro operation is not worth worrying about in my opinion. I got over losing gold long ago. They say it goes to seed.

I’ve slowly given what little I’ve ever had away to many people over the years. A little here and there. I just like being outside.

Would there be less 'Seed gold' going back to the tailings end if a long tom is used, say 20' - 40' feet long?

Depends on the volume of dirt ran and the time interval between break down cleanups. Of course also the gradation of the available gold.

The volume of dirt is going to be similar to the shorter sluice setup as there often is only one shoveling in both setups with the upside being longer time for the need of cleanout with the long Tom.
If the values sizes change back and forth depending on where one is shoveling in a given deposit it could pay to try to catch a bigger percentage of the finer graduation of the values in the deposit with the downside of a longer setup of the long Tom over the shorter sluice.

You are correct in saying there is going to be some seed values going back to nature.

I ran ten buckets, and it looked like it could go a lot lot longer with what I had. Thanks for the help. I wonder if there Is there a way to reverse mount a gold cube trommel so that the trommel tailings separate from the GC tailings...just thinking it would make going over the big stuff with a metal detector much easier.

Not sure of the separate tailings unless a hole is cut in the plastic
A picture may help?

If you don’t have lots of heavy concentrates, I’ve tested a corrugated rain gutter pipe to be as close to 100% effective at catching <sub gram gold. At least as good as I could weigh it on a sub-grain reloading scale. Larger pieces would roll out at the grades necessary to keep the “riffles” clean. I found the gold was limited to the first 2 feet of the pipe. I tested it with various quantities of small and fine gold up to 1/4 ounce per 5 gallon bucket of gravel. Was very impressed. They call it the “poop tube sluice”. Only downfall is the riffles will fill quickly with heavy concentrates.

Interesting and thanks for posting. I'm thinking one could drill holes to have the heavies pass to a second pipe maybe with layers of moss type of material for the heavies to wiggle through to the bottom?

The 1 1/8 hose barb fitting is what holds the trommel to the GC so it only makes sense to make a hole in the opposite side. I'll try and get some pictures here soon. I could of swore that Dan Hurd had his setup in reverse.

I didn’t get too scientific. Just cut an 8” dia. Pipe in half and screwed it to a board. Would catch flour gold incredibly well as long as it wasn’t floating. I used a plastic toat box w/electric pump. Divided the box in half vertically with swamp cooler matting to filter the water.
Tailing would go into a hanging tray with holes to catch the oversized material (which would be dumped). The fines went into the first half of the tote to settle out. “Clean” water was pumped from the other half of the tote to recirculate. I was able to take it into remote draws with very little water and run 3-4 5 gallon buckets of the good stuff before scooping some of the fine tailings out of the tub. Even ran it via a hose and a 55 gallon drum mounted in the bed of my truck.

Ok guys just an fyi. I read an Amazon review of the GC with trommel four stack where someone had the same problem. If you run a three stack it will change the side the GC tailings come out. it would then be opposite the trommel tailings.
