Two of my top teachers. Thats a pretty high honor comment Jay (wrt Jeff's) and you lost me several times in this one. Thankfully i can replay over and over to catch your knowledge. Im on my 4th time watching and am still kinda confused as to who won the box car derby lol. Perhaps a comment from the nut gallery is welcomed?? Bueler... Bueler..

Jason, you are a wealth of knowledge! Doing these expiraments is one thing, but being to verbally deconstruct the effects of them without arrogance in your tone, thorough inspection, and genuine curiosity with the ability to convey your thoughts. These are some of the reasons why I enjoy and subscribe to your semi comercial content. In any case, you are a great spokesman for the company!

@etarheel1 3 года назад

@robertwall713 Год назад

Wow what a wealth of information!!!, Jason, I have started performing smelting on my ore concentrates after watching many of your videos as they have given me the confidence to give it a try. I love the experimentation you perform and showing us your mistakes so that we can learn from them. I am sure some of this is by design, but your videos have given me a direction in gold ore processing equipment along with a corresponding reduction in my bank account, it is all good, Thanks again!

I spent my Career working Sand and Gravel Companies in the Central Valley of Calif. running the Gold Recovery Plants, doing a lot of R&D for Companies like Eagle Iron Works, Oro industries, Davaco, Barmac, until i became a Nevadian in 95, to raise my 4 kids in a free state..

@scotthack2632 3 года назад

Jason some of my Assaying instructions have instructed to add a reducing agent like flour which causes you to get more lead from the litharge. I don’t know if you’ve looked into that yet. You will be amazed, sometimes you can end up with too Much lead for your cupel pill if you add too much flour. You have to reduce the litharge… Pull the oxygen off of the lead oxide and that gives you your metallic lead. I don’t know how adding the oxidizer of potassium nitrate affects this but it would seem to argue that it goes in the opposite direction.

Hi Jason! Ive been binge watching your videos over past couple weeks. Lots to consider and take in. Ive never been able to get past crushing my rocks! Lol. Will your flux recipe work on high sulfide ore?

@nomana60 3 года назад

i'm getting ready to start melting some of my own raw gold and your videos, though beyond me in parts, are very informative and well thought out. question though, how does one identify sulfides? I know i have them because i roasted the black sands after tabling and could smell it.

@JustinQuilling 3 года назад

Very interesting. Do you split your samples or just scoop concentrates out and weigh them? From what I know, assayers usually split concentrates to make the samples uniform. I am just wondering how you do it.

@atcn1956 3 месяца назад

Excelente. Muito bom mesmo.

@scotthack2632 3 года назад

Jason I also noticed you’re not using lye any more, just the soda ash and the iron. I don’t know if that was in the previous video that I missed but I was curious about how you came to that.

@barthanes1 3 года назад

Really interesting experiment. I want to see if it works better using an iron bar vs. using iron filings.

@hairypunter6170 3 года назад

@Jason, Nice videos mate keep it going. Just a note, not sure if you did the maths, but the ratio of the PM prill against the Pb button is suggesting that the PM prill is heavier against the Pb button when more borax is used in the flux (divide the PM prill by the Pb button weight for ALL samples and see what you get :-) this also agrees with the colour of the prill (more borax, more yellow). It would have been good to zap the beads with the XRF or part them so see what the gold content was on all samples. Happy new year for 2021, Stay safe.

@Rob337_aka_CancelProof Год назад

You got to love this cool looking patterns produced by the bubbles in your tone mold and I don't mean like gas bubbles that rise in liquid I just mean like what happens in the mantle from convection currents or in the early Universe under expansion that causes matter to be concentrated alone certain areas where the expanding bubbles of space bumped into each other which is really cool looking. I wonder how we could get that effect on a t-shirt

@Rob337_aka_CancelProof Год назад

If your speculation is correct and surface area for iron is the biggest Factor I think iron filings is the way to go. Do you know anybody with a machine shop?

@miltondamiao6540 3 года назад

@howtoguroo2686 3 года назад

I have black sand in my creek mud , but no gold . do I roast the black sand to remove the sulfer , then pour that and borax and a chunk of lead , and the lead will trap the gold and silver ? then cupell the lead out ?

@chrisbrooks2062 3 года назад

My silver ore smelts I use 100% borax and get great yields, the separation of the flux is better than when I add soda ash.

@nobuntunglogopbonong7586 3 года назад

For me normally ... We put borax first ... We put 50% borax and 50% kalium nitrate on recovery of Silver ... Its recovery up to 100% silver from silver powder .. Sometime if we recover those incomplete treatment of Silver powder ( those leftover silver chloride, we use 10% soda ash before smelting and during smelting we use 50% borax and 50% kalium nitrate ... It will etch the graphite crucible a lot but we coukd recover up to 95% of the silver content

@ataali4279 3 года назад

Can i ask you . Can i melt black sand and ore gold and just use porax and ash sodium . And which better percentage for each other when i have one kilo of sand and ore gold ??

@daimitchell5603 3 года назад

An old coppermine(+ gold/silver sulphide) mine and on site smelter on a local mineral belt(NZ) was using a nearby quartz vein known to contain small amounts of silver and gold as their flux, quartz being silica - have you tried using small amounts of low grade quartz values containing silver and gold, as collector metals? - pretty sure they were doing long and slow(6+ hours) sulphide roasts and then re-smelting the cooled matte - so still many steps to assess for extra returns and losses - the smelter was onto it combining what was around to get the job done efficiently - another experiment perhaps ? - clearly you are in a good position to trial experiments of this nature - love your work and thanks for sharing your process and findings.

@richardoconnor7162 3 года назад

Things that come to mind, are you roasting off the sulfur first? The other would be to get a meter to watch you temps in the furnace. I find it funny that time of reaction is not being a factor?

@anotherrant6688 3 года назад

This is by far, the best, most informative video I've ever seen on this subject. Takeaways for me were you don't need tons of flux to concentrates to get results. You don't have to smelt it forever to get good results. Fill up the crucible as much as you can to maximize time, materials and energy. More matt equals less silver in button (which is what I want so I'm going to try that recipe). Questions: Did you roast the concentrates first? Can I use fishing weights instead of litharge? Can you do a video on cupelling in what I assume is an oven? I can't seem to successfully cupel with a torch and a portland cement cupel but maybe I haven't had enough gold in the button to get results in the first place. How do you know when your button is done aside from the blip thingy. Do you have to preheat your graphite crucibles beforehand? I had a couple of 'em pop on me.

@Rob337_aka_CancelProof Год назад

I'm not sure what the elevation is there but I wonder what effect pressure has on your results? Too bad you don't have a hyperbaric chamber or access to Sea Lab but one thing you probably do have access to is a higher elevation if you're close to sea level or vice versa if you're not and that's something you haven't factored in that might play a significant role so maybe next time you're traveling to someplace with a significantly different elevation and pressure than you're at right now take you some stuff to try out on the road trip

@aaronstewart3570 2 года назад

I don't like using Borax it's toxic, what's the equivalent bicarb ratio(Borax substitute) per gram of concentrate when smelting? My Gold is microscopic nanocrystals and hard to settle. Freshly crushed from high load ore in Australia. The smelt goes runny when 20% moisture is added to my flux mix but doesn't when it's smelted dry. First few test smelts, I managed to make green obsidian with gold and silver fleck through it. Looks crazy.

Have you consider using acid treatment on those lead beads before firing them in the small furnace? You can retrieve some silver at that point. It is over usd20 per ounce now Your last time experiment using electricity, should be a success, the problem is those black deposit you consider as waste are actually silver and gold (probably some lead too), checkout seetips channel, with the size of your lead button, you can do it in a tea cup. But beware of one thing, don't mix different acid together, aqua regis treatment of metal, lead, silver, even gold can become explosive in certain conditions, they are use in bullet primers.
