Rocks to gold part 3: Smelting the concentrates to a gold button


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

  1. wow!  I was expecting 20 grams per ton.  you doubled that.  so, It's 20 trips up the mountain and back.  And then you'll have an ounce of gold.  I think I'm a bit too lazy for that lol.  Thanks for showing us this.  It's very instructive.

  2. Your videos are really good stuff. I liked especially the smelting of black sand stuff. I have one comment anyway; There is an article in Gold Refining Forum from metallurgist, who works in gold industry, about smelting. He wrote that it's virtually impossible to recover all the gold that is left in slag by gravity methods, or even leaching. No matter how fine one mills it. He wrote that only practical way to recover it all is to use the slag in a next feed. Hope to see more stuff from you soon.

  3. I could watch that all day.  From nothing to gold!  Did you ever get the purity of it checked?  Wonder how much silver was in there.

  4. Thanks for the video, very Informative, i have 5 claims out west, just waiting for some more investors to come on board, but very excited about doing this, can't wait to get out west

  5. Thank you for taking the time to do these three videos.
    The series was very interesting and informative.
    First time I've seen the full cycle.

  6. Hey great stuff. I'm new but are you close to the Virginia side ? I have ALOT of quarts an other rock around me plus have gathered some samples of which you can clearly see the gold or what looks to be gold I know the difference between pyrite and gold so it's not pyrite but if you're close I could use some help on it

  7. I hope you respond. I have sat and sat watching your video's. I am working 3 tailings piles from 200-300 yr old mines. I have truck loads of pyrite, that I toss away. Am I tossing gold away. What I gather from your video's is there is also a little gold in the pyrite. I crush with a rock crusher, run through a 5 tear gold cube, pan light weights off, take out magnetite and smelt. I get alot of tiny specks stuck in my slag. As I understand the little bit of pyrite I miss burns up during smelt. I have taken to have stuff acid tested[since I dont have here] Guy said 18k. I kept getting gold specks stuck in slag, got tire of wasting so ship to a refiner in Colorado, never any response, then shipped to refiner in Binghamton NY, He said nothing in what I sent, try again. I really wish I could get some answer's. I know I have since I have gotten some buttons from my smelting's. Can you spare the time to help?

  8. Love your tenacity and very informative video. May I make two points: First, since the same flux was used with each test and visible gold was present in the slag, might I suggest you also test another flux mix to compare? There are literally hundreds available. And , second, I guess you have noticed the typo error on the Legend Refining Flux label in the chemical formula for potassium nitrate, KNO3, not KnO3 (sorry I can't do a subscript for the number "3".)

  9. I have some gold material .and I have tried to get a button I just can't seem to get it .will somebody get back to me I would appreciate if someone would show me how .I will pay you a fee .thank you

  10. Can you throw any old rocks in a smelter and extract the metals from it? I got alot of incredibly fine gold i cant for the life of me extract and im wondering if i melt my concentrates down ill be able to retrieve my gold rather than a mercury set up asking someone who has more experience than me hahah
