    Tips for sluice build

    Hey everyone I’m looking for some tips on a cheaper high bank sluice build I’m putting together. My thoughts as of right now (Keep in mind I’m keeping it very budget friendly), is going 10” wide 36”-48” long with Gold Owl matting. I’m making everything out of wood and I’ll have a little 72cc gas powered water pump and 3/4” pvc piping for water delivery. I’ll have the jet holes in pvc shooting up as well as in from the sides.

    I’m looking for tips on how much water flow I should aim to have. The pump does about 2300 GPH.

    roughly what angle should I have it at? I’ve heard 1” drop per foot.

    Is 10” too wide?

    I’m building it all out of wood to save some money.

    ALL TIPS APPRECIATED! I plan on building it tonight.

    Thanks,

    Adam

    Build it for the gold you are trying to catch. More variations will give you a wider range of recovery. You can make it however you want.
    Carrying it around and building your settling ponds will be more work than anything.
    Where are you mining?

    Another thing, I’m in Ohio so the gold is very small some pickers. Will that much water flow make me lose the flakes?

    As long as its compatible with the system and all works together should be fine.

    Should I just use the ribbed matting or should I mix it up with partial miners moss? If so, should miners moss be upstream or at the end of the sluice?

    Youre going to get as many answers as there are people who reply. There are lots of theories of how to best capture fine gold. The thing is, most of them work just fine. Some are worse, some are better but theres not really a "wrong" idea as long as its not a completely slick box. Testing has shown you can put sticks and rocks in it and still catch gold. Most of us are just quibbling over recovery percentages. Like Johnny said above, have some variation. large mat, small mat, riffles, moss... build it how you want it.

    Box angle and GPM are interrelated. Slower water makes it easier to trap smaller gold. Water should be fast enough to keep the cobble rolling out of the box and the concentrates fluid ( aka "dancing" ). Every change affects several other things so you are going to have to play with it. Periodically stop and pan some of your tailings to check for loss. A few colors isnt bad. A lot of colors or any flakes means to need to rethink something.

    No matter what you do...you will be changing it to meet your liking.
    You can always narrow a box...easy with wood.

    Like many above say, you'll get different answers from everyone, including me. But one truth is universal, the longer the better. It gives the fine gold more time to settle and places to get caught. The big stuff will take care of itself.
    My disposable opinion is to use more than one type mat or capture media and you'll have to try different angles and flows until you see your best results.
    Watch Gold Hogs videos and you'll learn much for setting up angles and flows.
    Start here.




    Good luck and let the fun begin.

    Too much water is a good problem to have...easy to restrict or idle the pump down.

    Just remember to make a spot for the bigger pieces to get trapped at the head of the box...and that if the box doesn't flare out..the velocity is going to increase as it gets longer making it more difficult to catch the fine gold at the tail end.

    The popular new style of rubber matting...I have my opinions which I will keep to myself. Adding it into a sluice box means slope changes WILL be required which may not be compatible with the other more traditional gold trap styles. You almost need a dedicated sluice run for that style matting so you can tune it.

    The thumbnail for the video is amusing...looks like someone is getting a garden ready.

    I'm a big fan of having some grate like this suspended above your box at the beginning to catch the pickers. Cover it with floating rubber mat that has been slit every 1/4" to keep the water smooth. It should catch almost all of them before your riffles or expanded steel.
    Then you need to concentrate on the fine gold.
    It's crazy but the amount of box shown in this picture catches at least 80% of the gold that we find. The next 3 feet not so much.

    EDIT: This type of trap will be unnecessary if your after flour gold. Great for trapping pickers and nuggets.

    3/4" pvc is probably too small for a 10" sluice, what is the outlet size of your pump?

    I was just thinking about that..2300 gallons per HOUR...38 gallons per minute is not enough to run a 10" wide box if I'm not missing something?

    I think it should be enough, my buddy has an electric highbanker with a keene a52 box that runs pretty good on what I thought was a 2300 gph but I could be wrong. His spraybars were 1.25" pvc. I could be all wrong. My highbanker hopper on my 10" wide sluice has 1.5" pvc manifold with 1" spray bars. If you can locate a Honda WX15 pump I highly recommend it works great with a 10" wide sluice, I found mine at a pawn shop.

    For reference the WX15 pump is rated for 74 gallons per minute.

    Tons of excellent information guys. It’s highly appreciated. I was wondering about the 3/4” pvc too. The outlet side of the pump is 1”. I’ll replace the pipe and fittings with 1” then. So 2300 GPH would Possibly be too slow for a 10”? I don’t want to have to rebuild the sluice around the water pump engine so maybe I’ll just go smaller. Is an 8” wide a decent size? I will probably go 6”-8” and just make it longer.
