So we are very excited because we finally have a system in place here to run these circuit
boards. And I have four different bins, I got back from the scrap yard and picked through
their electronic boards & circuit boards. And I tried to separate them into four different
categories. This bin, they’re all brown on one side and green on the other, they look
like they’re older boards, some have a whole bunch of stuff on them. I think that’s the
low-grade stuff. Here’s the next separation I did, these are green on both sides, but
they don’t have a whole lot of stuff on them. They seem to be smaller pieces, here’s
an old clock maybe, or a VCR. This is the next grade. Here’s the next grade up from
that. This stuff has all kinds of solder and wires. And there’s a chip with a little
gold corner. And you can see here in the light that’s all, I think, copper wiring, so there’s
a lot of copper in that board. And this is the highest grade stuff, and I’m not quite
sure what all this came out of, but you can see a lot of gold corners in these heat sinks,
I think there’s gold as well. All these different boards, some of you probably know
exactly what these came out of but there’s a little gold chip corner, there’s another
one there on this board. Here’s some more, there’s another gold corner. So what we’re
planning on doing here, here’s our system, here’s our hammer mill, bolted to a couple
ecology blocks. A shoot down onto our shaker table.
And it’ll make 4 cuts here. This first bucket in this green tub is the waste, the tailings,
there won’t be any metal in left in that. This bucket here in the black tub is what
we call the middlings, that’s where most of the the copper will go, and maybe the solder
as well.
And then out of these two ports here, this one on the left is the highest grade, that’s
where all your free gold is going to go, and all your most very dense stuff. And this one
here is called your number twos, and these are your two safety grooves, and the material
that is the heaviest but not quite heavy enough to get into the gold hole number 1 will get
into number two.
And there’s the system, it’s a hammer mill and a wet shaker table. And I’m going
to start with the lowest grade stuff, what I call the lowest grade stuff, and we’ll
run all that, show it running on the table. Step it up to the blue bin, and then go all
the way up to running what I call the highest grade stuff, and whether it’s the highest
grade stuff, we’ll see.
Anyway we’ll get this going here and show you how it works on the table.
So here’s a sample out of our number three hole, or the middlings hole. And you can see
there’s a bunch of copper in there but it’s also mixed with a bunch of boards still. And
for this first trial run, we didn’t have the splitter in the right place between the
middling and the tailings. So you can probably clean that up quite a bit just by adjusting
the splitter. This can be re-run on the table again, and upgraded even further, so you can
get it quite a bit cleaner than it is now.
This is the gold pan out of our number 2 hole. You can see it’s pretty much pure metal.
It’s a lot of copper, a lot of solder. But I don’t see any pieces of board or epoxy
or anything like that. It’s all metal.
And that gold pan there out of the number two hole, there’s probably 20 or 25 pounds
of stuff there. So it’s pretty dense stuff.
And here is the stuff we panned out of the number one hole. Here’s a close up of that
gold line. It goes all the way across there.
Here are the screens we use in our hammer mill. And the one we have installed for the
test we just ran is this screen right here. It’s a half millimeter laser cut slot,
⅜ AR, 400 steel. And we got about 50 pounds per hour, plus or minus, through, with that
screen size, so we’re still in the experimental R&D phase. We have some different size screens,
this one is about a millimeter, and this is a larger one at about two millimeters. So
we’re going to play around with trying to get the throughput up, maybe we don’t have
to grind it as fine as we did, or maybe there’s a two step grinding process, where you grind
it down to 2 millimeter for the first hammer mill, and then through a half millimeter.
But we’re going to keep working on this and we’ll keep you updated as we go.
So there’s the results of our tests, and we ran probably fifty or sixty pounds of boards,
and ended up with probably close to 25 or 30 pounds of metal out of them. So there’s
a lot of metal and valuables in there.
