Hi, my name is Jason Gaber with MT. Baker Mining and Metals
We specialize in building and designing custom mining equipment for the hard rock miner
Today we are going to demonstrate one our units behind me
consisting of a 4" x 6" jaw crusher,
a 20 inch impact mill
and a 4' x 8' shaker table
here is our morris 4" x 6" jaw crusher
you are looking at the feed tray here
and down the jaws
it's run by a 110 220 volt single phase motor
the jaw crusher here can discharge between a 1/4
and a 1/2 inch in size
depending on your ore hardness and size of your feed
and characteristic of your ore
it will do between a 1,000 and 2,000lbs an hour
this is our impact mill, it's run with a 16hp gas motor
the discharge feed from the jaw crusher goes right into the hopper
this machine can take up to a 1 inch feed
and discharges out of the chute onto the shaker table
and it can keep up with the jaw crusher at 1,000, 2,000lbs and hour
and it discharges 20 mesh minus
and our screen sieve analysis we've determined that
50% passes a 50 mesh screen on the first pass
and you can recirculate back into the impact mill for finer crushing
there is a step in the table
it starts right here at the end of the grooves
it carries up to the left
and there are four grooves
but the gold walks up the step
and up towards the water bar
The sulfides and other material can't make it up the step.
they form a band right at the end of the grooves
and work there way down into the midlings hole
and the tailings form a band behind the sulfides
and go down into the tailings hole
here is a couple buckets of the stuff we are going to be running
for a client here, it's just quartz ore
we have three of four buckets were going to run through and see what we get
you can see here the
the fine gold coming out of the sulfides the sulfides going down and into the left
the gold is coming over to the right
and out of the edge of every ripple you have your fine gold
and than gets in the long groove and walks right up the step
right under the sprayer bar
right at the top of the first groove
where the gold has worked its way up the sprayer bar
and gotten washed out
and works it's way parrallel to the sprayer bar
whatever sulfides make it up into the groove
with the gold are
down behind the gold, the gold is out in front
and it's work its way down
to the second groove you see there
up at the top there is a little pile of gold at the end of that groover
and the process gets repeated
here you can see the real nice gold line it produces
here is the material out of our cons hole after running about 100lbs of material, couple buckets
now were going to pan it down and see how much gold we got out of our hundred pounds
panned it down a little ways and your starting to see
some of the finer gold in the corners here
on both sides actualy
we are just going to be real careful and
keep panning down. This gold is real fine
some stuff in here that is 325
and smaller, 325 mesh and smaller
give this a swirl
you can see the fine gold
we weighed that gold you saw in the pan
15 grains, 15 grains out of a hundred pounds of ore
is about 0.6 ounces a ton
so if you have a pile of ore
tailings, dump piles that you would like to have sampled
you're more than welcome to send us a sample and we will run through a system similar to this
and send you the concentrates, tailings and the midlings back for you to assay
if your interested in a system like this please give us a call

Thanks for watching!
