Copper and Aluminum Recovered From Copper Chop Granulator Waste With MBMM Hammer Mill & Shaker Table

Hey guys, my name is Jason with Mt. Baker
Mining and Metals. And we have a super cool sample to run today. I’m super excited about this! This is the waste, the leftover stuff from
copper wire granulators, so how this works, is they chop up the copper wire into real
fine little pieces and the copper comes off an air table, and the copper is heavy so it
goes up the plastic and the paper is real light so it comes down into the tailings,
but they lose a lot of little tiny copper wires and little hairs and little flakes and
copper dust into the waste. So we are going to take this material and
run it through one of our 16″ x 12″ hammer mills behind me, it has a 2 millimeter by
1 inch long slot in it, it’ll help wet it and break up the little hair wires and stuff
with hooks and liberate the plastic from the remaining copper, come down onto the shaker
table, the coppers going to come across to your left into the number 1 and number 2 and
the 3 and 4 should have most of the plastic and paper goes down into the waste. So, we will run this, super excited to see
what happens and hopefully, we can recover quite a bit more copper out of the material. (machine noise) So what we’ve got here, we’ve
stopped the table in the middle of the process of running the granulated copper chops and
what we can see is, a high percentage of copper coming out of the top two long groves, working
over towards the left, under the water bar. And then, further, down the table here, we’ve
got a little bit of leftover plastic, most of the plastic ended up down in the number
4 waste but there’s a little plastic, that multicolored granules that you see coming
down into number 3 here, and then, starting on the second long grove we’ve got those white
flecks coming out, they’re less dense than the copper because they’re coming down the
table, instead of across the table. There’s more in this grove here and you can
see them the same operation here with the copper migrating to the left and the white
flecks migrating pretty much straight down the table and as it turns out those white
flecks, those are the aluminum components of the granulator waste. And before we ran it through the hammer mill
a lot of that was foil and some of it was actual wire, but a high percentage of it was
foil, so coming down into number 2, we’re catching virtually all of the aluminum in
our safety groves and a little bit of the leftover copper and so coming into number
2 is a high percentage of the aluminum and then coming into number 1 is a very high percentage
of the copper and its almost absolutely pure little granules coming into number 1 of the
copper fraction. This is really a remarkable success, there’s
a huge amount of valuable copper material in the waste copper chops. (machine noise)
All of it’s fairly small, there’s not any number 14, 16 in this it’s all, like com wire
or extension cord wire that ended up in the air separation waste material. Okay so here’s the results from our copper
granulator test. This is the waste from copper granulators. And this is super, super cool, so this is
our number 1 fraction, it is pretty much pure copper, there’s hardly any aluminum in there. We ended up running 29 pounds of the material
and this is 2 pounds exactly of copper, so its about 8 or 9 percent of the weight was
copper. This is our number 2 fraction off of the shaker
table, and it’s mostly aluminum, there is a little bit of copper wire that ended up
in there, but this is still very, very close to 100 percent metal by weight. And this is 1 and 3/4 pounds of metal in our
number 2, so when you add them both together you get 3 and 3/4 pounds of metal, came out
of the material. That’s right around 13 percent of the total
weight of that granulator waste, still had metal fractions in it, so this is a huge,
huge amount of value that people are throwing away, that we actually can recover with our
shaker table and our hammer mill. So I am super excited to see the results,
I think it was an absolute perfect test, the results are great. We saved some buckets, we are going to play
with some different screen sizes in our hammer mill, I think the hammer mill is actually
important to help break up the paper and the copper and the fluff, uh there was one point
where we tried to feed it right onto the table and the material floated off, so it needs
to be wetted or mixed somehow, but I think we can get a huge throughput and recover a
whole bunch more metal for these guys that they are losing and throwing away right now,
so. I hope you enjoyed the video, there is going
to be more to come, hopefully, we can get a bit more efficient at it and I’m really
looking forward to seeing you guys in the next video. So thanks for watching.


  1. The best way I found to get the copper out is to run it through a powder mill, then feeding into air spiral seperator, for a dry method

  2. I really need your help,I am having a copper granulator and separator,but my crusher is making the size too small,as we are processing different wire ,can you guide me what would be the distance between flying blades and fixed blades? Thanks in advance

  3. You're doing God's work here… Been trying to figure out how to separate copper from aluminum ad this has helped a lot… Could "Eddy Currents" refine the process even more?
