We have some ground up
printed circuit board material
that was sent to us, we are going to run it on the little 2 foot shaker table
the tailings here which is going to primarily
fiberglass, glass strands, epoxy, resin
and the plastic material
we are going to capture that in the pillow case bucket here
and than next to it is the
concentrates or midlings trough thats going to have mostly
copper and soder in it
and than on the end with have the third hole on this table which is the high grade
number one hole
we are going to run this material and see how it turns out
Now we are really getting some pretty nice separation
down here we have our
light material, the grey green is our printed circuit board material
coming across the grooves we have a lot fo the copper
and than
and out the longer grooves coming up under the water bar
we have mostly what I think is soder
and I expect after a little bit we will have some gold coming out as well
Now we have some gold coming down the table
right at the leading edge of the grey material
and I think that's going to increase as we continue on
over here on the left we have primarily copper
and soder
further down over here we have material flowing down over the grooves
The very light material, it's the
glass strands and epoxy resin
and that is going to the waste tailings
Now we are at the leading edge right under the water bar
and down most of this we got
a show of fine gold
most of the copper is coming down here
into our concetrates trough
there is a good view of the
blue green fiberglass epoxy material that is mainly the board material.
here is an overall view of the separation right up on the far left
we have a thin yellow gold line
and than a thick grey line right behind it
and than further to the right
you have the separation of some of the sodder and the copper
and than far to the right is the
blue green, epoxy fiberrglass material
Here is the gold out of the number one hole
there is a lot of that grey material down there
and there is a close up look at it
we have received our assay results back from
the shaker table test we ran
we sent our samples off to American Analytical
in Osborne Idaho, they are our assayers, they do a great job
We did a 48 element ICP
and some fire assays with the precious metals with a ICP finish
as you can see, there is a lot of information here, I'll just scan over it real quick
the elements that were tested
are listed there in parts per million
as we get down here to the bottom there is the gold, silver platinum,
palladium and rhodium
That were fire assayed and the platinum, palladium and rhodium were ICP finished
and I will go over
the percent recovery of the shaker table first
and than I will review how I ended up
coverting ounce per ton
and parts per million to percent recovery
I have picked out the metals that I was interested in
The list there is on the top
going from left to right is gold, silver, platinum, palladium
and than aluminum and down here is in pounds
as well, so aluminum, copper, iron, nickel, lead
antimony, tin
tanallium, titanium and zinc
and here along the bottom are the percent recoveries
we combined the high grade and the concentrates
to find the percent recovery, gold was 85%
silver 98%
platinum 89%
palladium 87%
aluminum 28% but that's not surprising because aluminum is light and not worth that much
copper 97%
iron 82%, nickel 96%
lead 92%
This was a surprising one, antimony was only 18%
tin 92%
titanium 78%
and zinc 89%
Those are the overall results
of the shaker table test
we are very pleased with the percent recoveries.
We think these can also be increased by fine tuning the table
and a even feed will help
maybe some adjustments to the table tilt
Those are the overall results
now I will go into detail about how I calculated.
the percent recovery
and we can take a look at just how I got these numbers
Here is a sample calculation, we are going to figure out the percent recovery of platinum
from our PCB test using our shaker table
and these are the three
bags we sent into the assay office
these are your dry weights in grams
these are the results of the assay, bag 1 had
0.342 troy ounces per ton
bag 2, 0.048 troy ounces per ton
bag 3, 0.006 troy ounces per ton
and both of these were given to me by the assay report
To find percent recovery
we take our bag weights
our sample weights and convert them from grams
into short tons
were in the United States, we use short tons
which are 2,000 pounds per ton
There are 907,185 grams in a short ton
so the grams go away and you end up with short tons
these are all very small numbers
than you can multiply your troy ounces per ton
by how many tons your sample weighed
and you end up with true metal
in that sample, so there was 1.3
I've gone to scientific notation
1.3 times 10 to the negative fourth troy ounces
of platinum in bag number one
I've done that for both bag number one and bag number three
and this is the key right here, this is the total amount of metal
in troy ounces
in all three samples, all three sample bags combined
you end up with 2.5 times 10 to the negative 4 troy ounces
Now we can ifnd out our percent recovery
you take the amount of metal
in bag number one and divided it by the total
amount of metal in all three samples
bag number one had 52% recovery
of the platinum
bag number two had 36% recovery of the platinum
and the final bag which was the tailings
we had 11% loss, I had recovery but it's loss because it went to waste
when you add up bag one and bag two
52 and 36, a little rounding error in there
you end up with 89% recovery
That is my calculations
for percent recovery
and using a spread sheet, I did that for all the metals
we saw that earlier, so that is the
that's how I got too the numbers
we are really impressed on the recovery for all the metals we assayed for
I appreciate all your support and feedback from you guys
a lot of guys have been really interested in what we are doing
Stay tuned for more videos
and we will catch you on the next one, thanks!
