My sugestion exactly! I think the powdering phenomenon is a combination of two things, the first of which being all off the stress of thermal shrinkage layering from the outside in as the glass cools, making the inside want to shrink but the ourside is already rigid. Imagine the dust a Prince Rupert's drop explodes into. The second contribution to the phenomena being something like oxidation, where as the really thin layers of the slag oxidize, the stress is relieved and the layer falls away from the outside in revealing the next, and so forth. There may even be a third, or more, stage in there somewhere. What a fascinating thing, a solid powdering itself! I can imagine a few applications for the phenomena, if the variables of making it can be controlled.

Sulphur (s2) has a reduction potential of -0.407, which goes more negative with decreased ph up to -3.1 with two free electrons, you need twice the oxidiser with oxidation potential >+407 to make oxidation of S2 the primary reaction, per atom of Sulfur. Most are explosive at assay temperatures. Interestingly iron reduces the Sulfur with its superior -0.7 and balanced two electron transfer forming FeS. I believe your artificially creating a VMS type geology making matte, and like VMS exposures it rapidly hydrates, but the chemistry does not leap into sulfide secondary and tertiary oxidation (h2s03, h2s04, h2s203+ etc) probably requires UV / ozone for that, thus your conundrum🎉love your videos, billy

@@frankenscience3553 there is no problem, Jason’s all over it, adding metallic iron reduces, S2/Sx repeating lattice to FeS & adding sodium carbonate to adsorb pesky FeS into slag layer, locking up sulphur from interfering with precious metal recovery. In this example he deliberately omitted this part to observe matte formation ie sus the sulfide content, likely assess how many nails he needs for a bigger smelt & qty of NaCO3 req, he even states so omitting the sodium carbonate which would mask the total matte formation, he is ‘free forming’ it to find the right mix for that ore rather than following a fixed ratio solution and failing (having a partial matte layer still)

In theory, you can develop a system similar to a retort for collecting sulfur and other gases produced during the roasting process. A retort is a closed vessel used for heating substances at high temperatures, with the aim of collecting volatile components produced as byproducts. In your case, instead of mercury vapor (although there may be some), the system would capture sulfur dioxide and other gases generated during the roasting of sulfide ores. This can be achieved by designing a closed system where the sulfide ore mixture is heated in the presence of excess iron(III) oxide (3:1 ratio) to provide the necessary oxygen for oxidation reactions. The gases produced during roasting, including sulfur dioxide, can then be directed to a collection chamber or system equipped with gas collection mechanisms. The collected gases can undergo further treatment, such as scrubbing with alkaline solutions (Sodium Hydroxide), to remove impurities and recover valuable components. Additionally, by controlling the atmosphere within the retort-like system, you can minimize environmental emissions and ensure the safe handling and disposal of byproducts. This approach offers a sustainable method for metal extraction from sulfide ores, allowing for the recovery of valuable metals while mitigating environmental impacts associated with traditional smelting processes. However, careful design and implementation are necessary to optimize the system for efficiency, safety, and environmental compliance. The main talking point that prompted us is the fact that an iron(III) oxide (3:1 ratio with sulfides) will oxidize the ore without the need for an atmosphere, or nitrates that should be used sparingly. I see you add iron in some of your smelts, but it is likely better to add the iron(III) oxide from the get go. There are more ways, but we'll just leave it at that.

I did some research on this and have an answer. When sulfides are exposed to the atmosphere they can become hydrated. The combination of the water and sulfides in the atmosphere will cause the water to become sulfuric acid when exposed to UV light (ie sunlight). This acid then breaks down the structure of the slag which is why it falls apart. So it is really just a cool set of chemical reactions going on here. Let me know if this makes sense.

Yes, your problem is that the gold is bonding to the thiosulfate ions. Thiosulfate leaching of gold ore is sometimes used when the ore contains copper, which acts as a catalyst for the leaching process. You just need to break the S2 bonds first before anything else. Haven't you tried roasting the concentrate in air first?

The concentrates Jason is using here are from our mine in Montana that I gave him a couple of weeks ago. They are concentrates from our shaker table bought from him years ago. I am having the same issues in smelting these concentrates as demonstrated in the video. I am using his soda ash heavy flux with a collector metal but only recovering about 60% of the collector and some matte. If I'd get all of the collector back it would average out to about 1+grams of gold per 100 grams of concentrate.

I've had smelts do the same - I think its a hydration thing as here in dry Nevada it takes 2-3 weeks to do the same. I'm guessing that its the free sulfur that is hydrating - pyrite has more sulfur than 1 to 1 ratio (which is what would chemically go with iron). I have not done any testing, but I am guessing that it is that excess sulfur that is reacting with moisture and oxygen in the air.

While watching this, I'm in the middle of a cupelling run from one of Jason's 25 pound bags of "run of the mine" ore. 😁 I don't expect there will be any gold though. I saw absolutely no signs during panning. Lots of sulfides and magnetite. 55% loss in concentrates/collector metal, post smelt, also leading me to believe nothing will be recovered. If nothing else, I got really, really good at panning even the finest sulfides out of pulverized ore.

Hi, physics trained “RU-vidr” here. For the mechanical change in the black material, I don’t know for sure about this reaction but what I do understand is that there are states that matter can be in which are unstable. So under the assumption that it’s not reacting with the atmosphere, I suspect what is happening is that as the glassy stuff continues to cool to ambient, the preferred state is one that has an internal crystal structure that has a lower energy state. A more common example of this is when in the winter you spray your windshield with windshield washing fluid and your windshield starts off clear, but then pockets start to switch to solid phase. This switch or “front” continues to move through the fluid changing it from an unstable equilibrium in supercooled liquid form; to frozen solid. The alternate explanation is that you crunched it up to play a joke on us ;)😅

@B0BBYL33J0RD4N
@B0BBYL33J0RD4N 3 месяца назад
Awesome video, always good to see you doing well. What I would look into would be finding out if the hydrated or non-hydrated sulfides are soluable in something easy to access. If you get 10 lbs of matte layer, and can get it to break apart into something you can deal with (maybe some acid can drive the sulfer out and make it into a different, more smelt happy mineral). I see you always trying to reduce steps by changing smelt ratios, which is fair. If you can do a step in smelt to reduce the matte layer by half, then you have more theoretical recovery with fewer steps, but you might add a whole recovery phase, where you take your matte layer once it breaks up, and just pour it into a bucket or something. As a non-chemist, could even make it into an experiment. Try both hydrated and non hydrated in different things. (This bucket was hydrated and then soaked for 1 week in draino, this one was unhydrated, and dropped into a bucket of root killer solution for a week, etc) The hard part would be to calculate actual helpfulness. Either a measure of remaining problem layer after a smelt. Or if you get a large enough base sample, you could test recovery, cause if it doubles the matte layer, but that matte layer holds no gold, that is better than a 50% reduction in matte layer holding the same amount of gold. Issue is that you would have to run each test dozens of times to account for differences in each charge of gold per sulfide test assessed. Cause you might just have more natural gold in the draino test vs the root killer test, and you would not know. Goal would be to get your collector metal, matte layer, and glass layer, and then to be able to passively refine that matte layer.

I would be curious to see what happened if you used a magnet to split the black powder into ferrous and non ferrous. Is that powder fine enough to free the gold, or could it be ground fine enough?

If you want to get rid of your Matt from forming in the first fusion you'll need to add quite a bit of potassium nitrate Just doing a flux recipe; 100g pyrites 200g soda ash 50g borax 25g silica 100 - 200g potassium nitrate 30-50g collector metal (Potassium nitrate really depends on the amount of sulfur present, add 1g KNO3 for every 2% sulfur in 10g ore) Heat slowly to avoid boiling over as nitrate fusions can get a bit exciting

It would be interesting if you sent some of the black powder to Sreetips RU-vid, and how much the difference in yield would be in the refining process of Aqua Regia Process VS Cupellation.

Hey Jason, great channel it's very interesting to watch. Have you ever considered experimenting on your MAT byproducts with chemical precipitation. It might give you a general idea of the AU content that could be locked up in it ? Would be a good experiment to watch to.

I was taught to heat just the sulfides up to red hot and hold temp, breaks down sulfides and drives off the sulfur then dump in cold water to process left over gold..... thennit can be smelted

I probably don't know what I'm talking about, but won't acids and bases have a bigger preference for each other than what you were talking about?

I have to wonder if adding a button of collector metal at the bottom would be a benefit, basically a starting pool to help draw all of the collector metal "rain" to coalesce at the bottom.

You should timelapse the sulfide matte breaking down into that black powder

Do it again, but bake the powderized portion to drive off any moisture before smelting. I don't know what it'll do, but I'm curious.

Now that your mine is producing, it might be a good idea to look into manufacturing your own acids to dissolve impurities. Sulfuric acid is relatively easy, with tutorials you can watch on this site to learn the process. I'm curious how effective roasting, grinding, then gravity separating would be to remove sulfides.

What about roasting the sulfides to oxides before trying to smelt them? Would that improve the recovery?

So the sulfite is kind of an glassy material, maybe there is some sort of internal stress thats turning it into powder when they release??? I really don't know
