hey guys my name is Jason with Mount Baker Mining and Metals and with the way
the economy is going and the price of gold spiking I wanted to demonstrate
three different pieces of equipment today for you with a sample of gold ore
that we got from a customer and this these three pieces of equipment are kind
of specially designed for miners who maybe are on a budget or don't have
the size of operation that needs our 1 ton per hour turnkey system and so we're
going to start here with the 6 by 10 jaw crusher run by a gasoline motor then
we're going to take the sample over to our 16 by 12 hammer mill and run it down
onto our 4 bite shaker table to recover the gold
all right so now we've got our buckets of material we crushed with the jaw crusher
we've brought them over to our other equipment this is a 16 inch by 12 inch
hammer mill and with 0.8 millimeter screen it's going to grind our material
up to 70% passing a 30 mesh screen and about 50% passing a 50 mesh screen that
will liberate the gold in our in our ore we'll run it wet so a slurry is made that
runs down onto our shaker table and then the gold and the heavy minerals are
going to come across the shaker table under the water bar where they'll come
down into the number 1 and number 2 ports the sulfides are going to come down into
the number 3 or middlings port and then the tailings are going to flow down into
the number 4 port and those would go to your your waste or your tailings pond
and so with these three pieces of equipment the jaw crusher and then the
hammer mill and shaker table you can take run of mine or dump piles waste
piles and process them and get the gold out easily and by hand
because I'm taking our number one and number two off the shaker table and I'm
just gonna pan these down real quick and we'll see there's kind of the amount of
material we have a little bit of quartz on top but I'll pan this down and we'll
see about any gold we got in the pan from those two buckets okay so I've got
our stuff pan down to a little bit you know maybe less than a quarter cup and
I'm just going to kind of shake it out fan it out and there's our nice little
gold line in the pan okay and so there you go a three simple to operate easy
pieces of machinery you can take buckets of material and turn them into gold in
no time
here's our concentrates and seeing them in the pan and seeing that line of gold
in the pan is great but what we really want is we want a little gold bead that
we can end up selling and so I'm gonna work on getting these smelted down and
getting the gold bead so we've taken our stuff we're drying it out over our
furnace that we're gonna use for smelting you're gonna get this all dried
up we're gonna mix it with some flux smelt it add some collector metal pour it
into our cone mold and then get our collector metal with our gold in it and
then we're gonna cupel it and end up with a gold bead so we'll get this stuff
dry it out and move on to the next step
we got our crucible in there there's our iron rods there was 500 grams of
material I used 500 grams of anhydrous borax 500 grams of lye and 250 grams of
silica we'll get that all smelted down and get
our collector metal out of there and get it cupelled and I've got a ton of
videos on smelting of showing the process so you can check those out on
our Channel
get that respirator off there's our pour... poured pretty nice, slag
was a little bit thicker than I would have liked I think there's a little bit
of silica in the material so it may have thickened it up a little bit but it
looks nice and glassy from the stuff that ran over there and even if I get a
little bit running over all the lead and the gold is so dense that it just goes
right down to the bottom of cone mold none of it flows out into the slag that
runs over the edge so we're pretty safe there but well let that get cooled down
and take a look at our collector metal button at the bottom
alright there's all our slag from here down I'm sitting right on top there is a
pretty little lead button
and there's a there's our lead metal and that's separated really nice from the
slag alright now next step is to take that put it in a little cupel and get
all that led out of there there's a little lead button and it's
just about as beautiful as can be there's it separates awesome from the
slag there's no matte, I weighed it before I
used 54 grams of lead and I just weighed it again it weighs 55 and a little bit
more so we recovered all our lead plus a little bit extra so that's just about as
perfect to smelt as you can you can ask for and here's a little cupel the the
lead is going to oxidize in our electric furnace the oxides are going to get
absorbed by this magnesia cupel and once the reaction finishes all the
lead will be gone and we'll be left with a little tiny precious metal button in the
bottom of this cupel
and here's our little precious metal bead it covered that that's actually a
pretty big bead for just those two buckets that were three-quarters full of
probably only 75 or 80 pounds there and we got that pretty good sized bead
so let's get it weighed and see what we got
so there you go 0.99 grams out of our two buckets there and so you
can see how easy it is to run material through the system, smelt it, cupel it, and
get some gold okay so I wanted to talk a little bit about the spare parts for all
the machines we carry all the spare parts in stock and I wanted to walk you
through the different sets so these are spare jaws for the jaw crusher spare
jaw plates and you have the stationary jaw and the swing jaw here and they're
very easy to replace it's just a couple bolts to pull them out and replace them
and also these jaw plates wear pretty much from the bottom half and so as they
wear you can actually remove them flip them over and get a whole new set of
life out of them so they have two wear services you can flip this is one of our
screens for our 16 by 12 hammer mills and these are laser-cut slots here this
particular screen is a 1.2 millimeter slot and so for a typical
quartz ore you get 70% of your material passing a 20 mesh screen when run
through this screen here and then also we have a smaller screen a 0.8
millimeter and with that screen it's typically about 70 percent passing a
30 mesh screen this is also one of the hammers we use in both of our 16 by 12
and 24 by 16 hammer Mills this is a high chrome hammer and the chrome allows for
a much harder surface and better wear surface and in the 16 by 12 we use 20 of
these hammers and then the 24 by 16 we use 24 hammers so now let's go take a
look at our shaker tables so these are our two different size tables this is
the 4 by 8 which you saw run the material and it's a one ton per hour table we
also make and sell these five foot by 12 foot tables here that are 2 ton per hour
tables that we use in our two ton per hour turnkey systems so with the 3 pieces of
equipment that you saw in the video today really designed for a miner and a
budget there are three distinct advantages the first is by bulk sampling
or small scale processing on-site you get a lot of the information that you
need to go for the next step but you don't have to pay thousands and
thousands of dollars on assays to do so the second one is through your sampling
or bulk processing you actually recover the gold that's produced and you can
take that cash and invest it back into the business and the third one is the
equipment it's really like building blocks so you've purchased the three
core components of a turnkey system and if you prove up your site and you want
to expand in your milling production you really just need to buy the equipment to
automate the system so it's hoppers and conveyors so the last thing I wanted to
teach you guys with is we have a smaller system that we're developing
that you can actually take the ore from your site put it in and get gold out the
bottom but it's all run with gasoline engines and this consists of a 16 by 12
hammer mill and a sluice that you can put in the back of a pickup truck
literally drive it to your site and be processing the same day so I hope you
guys enjoyed the video if you have any questions or comments please let us know
all of which is in our description below so thanks for watching and we'll see on
the next one
