The Shaking Sluice Box

[Music] foreign [Music] shaking sluice or whatever I would call it it has the same idea as a lot of stuff I build it's on these flexure Springs and there's a motor and the motor shakes the table back and forth and I can shake it up to about uh seven Hertz this is Placer gold of various sizes and this is a 100 mesh screen and I want to get out you know I'd love to get 100 milligrams of 100 mesh minus I don't know if there's anything in here or not tell you the truth not sure what's in this because I've never tried to measure it so I'm using the 100 mesh screen just to screen whatever comes through the black powder black sand okay so the gold is actually bigger than most of the gold is bigger than 100 mesh and take a look at this with my microscope here's the magnifier so if you haven't seen this uh in a previous video I covered it in some detail so here's what the 100 mesh minus gold looks like so I was going to weigh it to see how much I recovered but obviously that is going to be a problem so the pattern that you see here I'm still working on it but this is working pretty well I I might add some more Chevrons here they terminate here so these Chevrons terminate here and these lines are just sort of protection some of the gold will go into the first couple of grooves and then hopefully nothing gets down into here so there's a battery power supply that runs the pump and the shaker there's a tub of water there's another tub of water that catches the tailing so that I can run them through over and over again if I want to the water comes out of here this pipe is just this is nice because it distributes the water flow evenly I don't even know exactly why it works but it does and um this prevents splashing and the tailings go out there and into the tub so it's a closed circuit system I have a bucket of uh crushed sand this I crushed it using a stamp Mill that I'm developing it's um any nowhere near finished in fact it's got plenty of defects I'll show it to you in a sec but this is the crush this passed through a 30 mesh screen so here's the Stamp mail it's a work in progress right now only I can only get one stamp one hammer to work at a time there's a lot of mechanical issues with driving the yeah lots of stuff I'll cover this if I did it to work I'll cover this in other videos it's a very interesting machine and I think it's got a lot of potential so here's the gold again that I just weighed out in that black sand and I'm going to put it all into here and there it is and it's as usual it's floating on the surface the gold almost all the gold is like floating on the surface so I'm gonna go get some Jet dry having Jet dry in the water is extremely important so our little tiny bit of gold is buried in this kilogram of crushed ore oh it took me about two minutes to go through kilogram of the freshwater so as a continuous process I could probably I'm guessing with this tiny little table I could run 50 kilograms per hour you know if I were at the beach or something where I had a continuous float material now here's the fun part we're going to try to clean this up and find the gold I'm going to Snuffer up these top grooves the Chevron grooves and I'll show you what we do with it lots of black sand caught in the first Groove and consider the bottom three or four grooves as kind of safety grooves so that we don't lose anything valuable all right so now we're going to go to step number two these are Pyrex watch glasses for you know beakers when you want to reflux um and uh turns out they're really really convenient for the next step so I pop the tube out oh man I can see very fine gold in there all right more careful all right so I cleaned the tube out pretty well all right now A Snuffer bottle just turned it upside down shake it and we're going to plop it out all that junk try not to lose any of it here's the cool thing about the this Pyrex it's got the right curvature to it you can use it as a miniature and potato pan now we're just going to shake this back down and we're gonna swirl actually swirling is better as you can see I'm still figuring this out but swirling works really well is I'm going to Snuffer up the rest of that water and get rid of that without disturbing the material at all that's important yeah so here's the fun part you can just turn it upside down and you can look for the gold and we'll bring this up here you know and there's the gold it's nice it's kind of magic so again here's the magnifier it Clips onto my cell phone case and we can take video and there's all the gold the really really fine gold is now easy to see right through the bottom of the Pyrex watch glass let most of the water get out of it and let's find out what we got there's a few gold particles in there as expected but much less than in the Chevron the ends of the Chevron I think pick up most of it and finally here's what's what was in the last four grooves combined so so there's a bit but it's not too much I wish I had actually just done the last screw I'm gonna have to try that here's the tailings from yesterday I'm going to run them on the table again to see what we lost foreign so there we have uh the second pass this is the tailings and I'll clean it the same way so there's a look at the Gold that we lost in the tailings the first time say it's um maybe 10 of the total
