Hi, my name is Jason with Mt. Baker Mining and Metals
and today we are going to run three different samples a customer sent to us
these all look like they are samples from electronic recycling
this is the first sample we are going to run
it has a lot of
customer said fer-rite dust and rare earth metals in it
you can also see there is some little copper wires
and some other materials we are going to try and separate by density
this is a second sample, these two I believe are together, this one is just a coarser fraction
looks like ground up circuit boards or some
sort of electronics recycling
the customer was a little closed lipped about exactly where these came from
and than this is
the third bag, I think it's just a finer screened fraction
there is a lot of copper wire in it
plastic, and I don't know if he is capturing aluminum out of this or what
we are going to run it on our 4' x 8' shaker table
and see what metals we can separate from the plastics and other waste
We have watered down the material down a little bit
so that it's not so hydrophobic
because if you take dry material especially electronic waste and run it on the table, often it will float
and when we run new samples like this
I like to start slowly because i'm not quite sure how the material will act on the table
okay we have run our shaker table a little bit here
and you can see the big
black band of black fer-rite
and it's actually dense enough its working its way up the plane into the number 1 concentrates
you can see this finer grey stuff which is probably lead or tin
working it's way up the cleaning plane coming down in a nice,
band right into the number one con
and below the fer-rite this is probably aluminum or your lighter base metals
and the copper wire surprisingly enough
has enough surface area that it won't settle into the grooves and the fer-rite
so actually a lot of your copper is going into your number three midlings
and than your finer copper and pins are coming into your number 1 and 2 mix
We are actually getting pretty good separation on the table
one of the advantages of fer-rite is that it's magnetic
without to much work you can pull it out with a magnet fairly easily
I'm not to worried about separating the fer-rite
from the rest of the material
we are getting really good separation of the dense heavier base metals, either lead or tin
and the aluminum is separating very nicely
I keep running the sample, i'm looking for any precious metals don't see any yet
we will run a little bit more than we will stop the table
and we will take a look at the separation we are getting
okay we are almost done with our bucket
we've stopped the table to see if there is any precious metals on the leading edge here
and I don't see any precious metals
you can see the clear band of grey that coming down into the high grade
I don't know if these are electronic pins or what
but they are coming to high grade as well
again the fer-rite is coming into the number one as well
I think we are going to re-run the number one on the table and see if we can clean it up a little
and isolate this light grey dense material from the fer-rite
we will finish our bucket here
we will take a look at the nmber one and maybe re-run it
here is the number one port from running our first sample
andw e are going to re-run it on the table and clean up some of that grey dense material
from the fer-rite
in that first run
i'm going to run it a little bit slower on the table
and see if we can clean up that grey material a little better
This is our second sample
we have mixed the two together, there was a larger fraction and a smaller one
and this one has some plastics in it that are actually light enough to float
so i'm just decanting the water off
the sample after we got it wet
A lot of the plastics are so light they float
we will run this sample and see what we get
we are about a third the way done with our second sample
and this looks a lot more like what we are seeing when we grind up boards
a lot of plastic waste is going down into the tailings
and than the heavier metals, copper, lead and tin sodder
are going into the high grade
the table is doing a really good job of separating the light plastic and the waste
flowing down into the tailings as the heavier metals work there way into the high grade port
because there is so much waste in this I can feed it a lot faster
this is our second sample and we are just about finished running and I don't know if you can see it in the camera
right along the leading edge there is little pieces of gold
all the way down here
going into the number one port
and that grey silver band is probably another lead or tin sodder
maybe it's a silver sodder i'm not sure
the gold is right at the leading edge of that
because it's the most dense its working its way in the number one port
it will be interesting to see what the assays are
from these samples to see if we are recovering most of the gold from our number one port
we have started to brush down the table
and usually as you brush down the table you get your best showing of gold
and you can see right on the edge of this grey stuff there is gold
pieces going all the way down there
there is some gold in this stuff
