We are back for our third installment of our
rocks to Gold Series and what I've done so far is that taking the gold pan with
concentrates and I've poured them into that coffee filter and let them dry
it's been a couple days they've dried out really nice
there's our material
here's our scale and I have an unused coffee filter here
which ways
Right about one gram so
I'm going to weigh the coffee filter with the material on it
weighs six grams
I'm going to take some flux
mix it up put it in our
number-4 crucible which is going to be a little too big but that's ok to work and
then I'm gonna put that on top I'm going to burn the coffee filter on top of the
flux in the crucible and i'm going to mix that material into the flux
so again i'm going to use our legend refining flux is just too pre-mixed flux it has
potassium nitrate in it as an oxidizer that'll help oxidized some of the
sulphides a little bit of junk that's left in there and I'm going to use
five times the amount of flux as there is material so I want to get a nice good smelt and have
plenty of oxidizer to eat up all the sulfides and junk in there so we have
six grams of material and i'm going to mix up i'm going to pour 30 grams of
this flux into that crucible
alright so I'm gonna tear the scale
Looking for right about 30 gram
there we go
31 worked well
i'm going to take that
Put it into our cruicible
You can take that filter
Put it down in there
I'm going to burn of the coffee filter off here now
because the content filter is carbon and the carbon counteracts oxidizer because
the carbon wants to soak up all the oxygen so I'm going to burn that off and
get as much carbon out of there is a can there be a little bit ash residue but
then the remaining stuff that's left after the burn
I'm going to mix it all in and get it nice and misogynist and then put in the
kiln ok here we go i'm gonna burn the coffee filter i'm just going to let that
all burned down to ash
we got all mixed in there and yes this crucible is way too big for that little
bit of stuff but it's the smallest 1i have so we're going to have maybe a
tablespoon or the stuff once that gets all melted down but will pour it into
our cone mold and see what we get
alright adjusted our pores there's a little tiny bit of stuff that report in
the bottom of the column old there so let that cool off a little bit and see
if we get a little gold button or just tiptoe around mold and shape slide away
and you can see there's our little old button there isn't better focus you can
see it didn't quite all combined there's the big piece and there's no little tiny
piece over here and there will be be there so I'm going to knock the the big
pieces out of there and then i'll crush up and pan the rest to make sure i don't
know 30 make sure I don't miss any little babies will get that knocked out
of there and wait and see what we get
so this is a great example of why should always save all your slag and then
recruit shit and
across the shaker table or some of the concentrator because you're going to get
little gold BB stuck in your slag and you don't want to lose those now one of
the reasons we got some gold babies and ours and I i don't think i got it quite
hot enough i was trying to do three or four pores there and I try to do a real
quick and I think this one I waited till the last one and it pull off a little
bit so if you don't have your material really hot it stays liquid but as you
pour it into the mold it cools down real quickly
also we hardly had any material here I think there's only about 30 grams with
the stuff we put in there including the gold so there wasn't a whole lot of mass
so cool down real quickly and then the third part is are conical mold really
designed for a little tiny amount of material like that is designed for a
full number ten crucible so there's not really a a cone at the bottom it's it's
it's pretty flat for that little bit of material so it it also didn't collect
all the material right now at the bottom of the cone but anyway so what we're
going to do is we're going to take all of our slag and this is actually one of
the first little rock crushing things i ever made this is just a type nipple and
a pipe cap and then I have a long bolt so we're going to put our slide down
there
crush it I have a 20 mesh screen we're going to screen it 20 mesh into the gold
pan anything larger than 20 minutes we're gonna put back in there and crush
the 20-minute screen so we're going to do that pick out all the little gold
bebes and then I'm going to take some oxy acetylene torch and melt it all down
into one single button so we can get it weighed here's our material through 20
my screen and i'm going to just roll that around in the pan and we should see
little gold BB shown up so here's those little gold beads that went through our
20s screen put my finger down here for scale there's some really tiny ones in
there so it's always a good idea to keep your slide and crush it and liberate the
little gold babies that get stuck in the slide if you have any
and normally i just put this in my bucket of slag and crush it later but
since you're trying to get a kind of a percent recovery on this stuff i wanted
to crush this little bit and we can melt it all down and you get all right so
there's all our gold and bb's hold the slides too attached in the bottom are
melting dish so I'm gonna add just a little bit of borax that to help it all
get nice and fluid and absorb some of that slag and trying to get the gold all
in one single button and then we can get it wait
ok here's your scale we've got our little gold button here after the melt 2
grams
this is a little reloading scale that we use for some of the smaller weights we
have it's all in grains so I'm going to take our little gold button 10 20 30 40
grains a little less than 40 grains going to get a 0 geral to figure out how
much it weighs
ok I got our level again or it
38.6 grains
alright so now we can calculate our percent recovery and this is obviously
assuming that that whole button is gold which is probably isn't there is
probably little bit of silver mixed in but for now this is what we got we ended
up with 38.6 grains was the way to the button which equals 2.38 grams and we're
going to do it both ways we're going to the American Way and the way everyone
else in the world does it so we get to . 3 grams or for the American guys we get
point zero seven six five troy ounces is how much that little button Wade
original buckets weigh 207 pounds which is equal to point zero 5 35 short times
because the short title is 2,000 pounds again the American Way so too . 3 grams
over the amount of short times we had
we ended up
the value of 44.5 grants pretend or announces its 1.43 troy ounces for time
so i would be pretty good about an ounce and a half again I gotta squeeze out
that thing up to two-and-a-half ounces so we're we're in that range this was a
fun one to make I not often do you get to take it all away from digging the
rocks how the ground to golden hand so this is a fun one company's liked it and
we'll see on the next video thanks again
