    Ultra Fine Gold Recovery

    I have several tons of material that I need to finish. Most of the material is 10 to 20 mesh or smaller with the gold mostly being 100 mesh or smaller. What piece of equipment would be able to finish this off with a production of at least a ton a day. Lots of magnetites and black sands too.

    Get yourself into a Gold Cube. That is exactly the kind of material it was designed for (and the volume of material too).

    Tons?? I would run it all throug a dry washer if its dry or run it through a high banker if its wet or damp. Just be very careful of your gpm. Real fine gold needs to be watched closely. Too much material to run. Are those tons all cons? Can't be. In lucky to get a half a bucket of cons! Lol

    It actually is reject sand. There are several hundred tons of it and it all has gold in it. Average of 3 to 5 one micron pieces per pan and then there are several hundred pieces of gold half the size of the black sand. This is in say 6 pounds of material.. Does anyone have an idea what the OPT would go on something like this? Just a guess...

    Based on what im seeing in the post, putting the info in my homemade calculator , i come up with .21 cents per pan, or .0418340107 O.P.T. / ($71.18 ) that is based on 100% purity, reduced to 70% purity puts it about ($49.83) per ton.

    Thats just the micron pieces , and you say ( several hundred pieces of gold half the size of the black sand ) not sure how th measure that.

    You might have a gold mine.

    I'd agree with Kevin about the gold cub, I was thinking the wheel but that kind of material you have I'd get a cube

    How about the under flow system by grumpy prospector. I was looking into this system for running some material. You could check his website out. I'm also interested in the gold cube as well

    Good question, since the gold cube combines underflow and vortex matting I think it is the best fit. It was designed for beach sand originally and built to handle the large volumes he is looking to run.

    I would say it depends how much material you want to run between clean outs. Ask Red or Mike (the guys who invented and sell it) for their advice. They'll tell you straight!

    You will still need a miller table or blue bowl to run the concentrates from the Gold Cube.
    They advertise the Gold Cube to handle a 1/2 ton an hour. So you could theoretically run 4 tons in 8 hours not counting clean ups.
    The stack of 3 should do fine. 4 if you want to go longer between clean ups.

    That'll work GG but a lot of guys (including Mike and Red) who use the Gold Cube just pan the result since it's only about 1 cup of cons per clean out. Mike Pung posted a description of his panning method in one of the streams on the forum in fact.

    That's why I was thinking about under flow system. It seems that you don't have to pan cons at that point. At least that's what's presented.

    i really like the idea of useing the Gold Cube, BUT will you have any help? 1 ton a day is a realistic amount of shoveling by 1 person. but with the Gold Cube youll need to do periodic clean ups as you go. and im not sure of the frequency of those needed cleanups. id say if this is the way you go,id do a cleanup on your first couple of runs to see if your loseing anything with your setup/proccess. then make any adjustments that are needed.the Gold Cube runs screened material real fast,but i wouldnt want to rush anything just to get done.take your time! 1 ton should go fast if your up to shoveling,and rerun that material into seperate piles! go luck,i wish i could be there to help!PLEASE post a picture of your results! and id save all that black sand to crush and rerun it seperatly also!
