If you haven't seen Sreetips on YT, he has a ton of refining experience videos - a great teacher. Nice job mate!

[@justinstolz4481]

Sreetips does another refining by dissolving the gold in Aqua Regia and precipitating it back out prior to melting. I'm not sure if this one is even two 9s fine without the AR bath

[@andrewthalerscrappy437]

Sreetips is very generous with sharing his information just like Jason. Both are part of my favourite channels.

[@GoodForYou4504]

Jason had mentioned Sreetips in a previous post.

[@johnwilliams8818]

Sreetips is such a good educator that I kept hearing him explaining what Jason was doing, except when Jason didnt "Do" something 🤣 Then I was like "HEY! You forgot to do something!" I was waiting for the Aqua Regia too, and a proper filtering of the shmutz from the suspended gold.

[@ManMountainMetals]

5000th sreetips comment, yeah, I 🤔 think he may have heard about him😂

[@Phoenix_Enterprises]

When melting the alloy inquart stir with a carbon or quartz stir rod to mix thoroughly. Gives a near perfect alloy every time. Check out the "flame polishing" technique Jason it's what the mints use. Nice mirror finish. Thanks for sharing

[@ZoonCrypticon]

@12:30 sreetips always stirs the molten mixture in the crucible, so that the silver and gold reach a finer degree as inquarted alloy.

[@beforethunder4987]

Man, I knew I should have payed attention in chemistry class lol. So cool to see how all the different elements react with each other and burn off what you don't need. Cool video, thank you Jason!

[@redbaronrefining5322]

Friendly tip Jason; When using nitric, keep your heat on low, add nitric, and once reaction slows down, then bring the temp up. There are 2 main things you’re doing that is wasting the nitric. 1: boiling the nitric will cause it to evaporate off/be consumed 2: not using a watch glass (cover) on top of the beaker causes the nitric to burn off easier. When you use a watch glass, not only can you monitor fume production to help you with determining if nitric is working still, you also get a nice distillation effect that causes the nitric acid to pool up into droplets and finally fall back into solution so you “recycle” the nitric and that same acid goes a lot longer. You can always boil the gold in some nitric if you want to clean it up a bit after the melt, although going straight to agua Regia after the inquarting process is best. Great work regardless, it’s a bit of a tricky process that takes time to get down to a science :)

[@SpiritualNerdGems]

Good call seeing as nitric acid boils off and reacts with atmosphere making it less efficient

[@keithstudly6071]

I think that any High School chemistry class could benefit from seeing this. Nice to have a general overview of a process who's results you are familiar with.

[@tommyfreelander]

Lady asked “Why are you watching that?” Me: “I love learning and watching people learn :) “ Great video Jason! God bless

[@Michael-rg7mx]

I wore a half mask most of my career. Check with your supplier or read the directions. My cartridges for acid vapor were only good for 1 day. He told me if I'm using it intermittently I could stretch it to 8 hours of use if I took them off immediately. Taped over both sides and sealed them in a freezer bag with desiccant. Write on the bag how long it was used each time. They suck impurities right out of the air as long as they're exposed. You don't want to end up on oxygen at 50. Change those filters.

[@hpdepasse5997]

your gold look nice finaly, but you may try with aqua regia : muriatic acid + a few ml of nitric to dissolve the gold only, filtered, then precipitating it.

[@shannel318]

You are a master at this!! Thank you for sharing with us, refining is an amazing process!! I wish you were the new “science” guy that would be required in every high school and college classes!! About time younger generations learned how and where all their gold and silver comes from, especially since it’s in almost every electronic device they utilize on a minute by minute basis!! Thanks Jason!! Keep sharing!⛏😃👍

This is your unique content. I want to see larger scale crushes, liberation and recovery! 10/10!

[@kellyw.1779]

Hey Jason! Wow, this is so cool to see how you get all the gold and silver separated. Love seeing the solid chunks and buttons!! Awesome...

[@fredolney9595]

Jason I think this is one of my favorite videos. You have perfected your refining techniques and this is the best.

[@OwlTech333]

Excellent work Jason! I would love to see you performing the Parkes process and explaining it as you always do, I can definitely use some visual instruction.

[@B0BBYL33J0RD4N]

When you were asking about the mix, if you were having an issue with the non-disolving stuff, just add more silver In terms of silver efficiency, it is better to use the exact right ratio. In terms of best purity, use an abundance of silver, as a well mixed alloy can still have pockets of high gold density. If you use more silver, it might mean the acid has to eat through 4 molecules of silver instead of 3 per gold molecule, but the more dense pockets will actually clean up better. I think it means the difference in 99.9 and 99.999% but

[@CuttinEJ]

When you inquart you really need to manually mix the metals thoroughly to produce a homogeneous alloy. To finish the refining process you need to dissolve the gold in HCl and Nitric, then filter until the solution is crystal clear, then precipitate. Precipitation can be done by any of several methods, but SMB is the easiest. After precipitation the gold powder needs to be thoroughly washed and then you can melt it in a properly glazed dish.

[@salishseaquest7952]

Jason, this was fascinating. To see the entire process with the added repeats as you determined what was next was incredible and beautiful to see. Quite a dangerous process, handled by an expert. Thank you for sharing it all.

[@rindapelton5876]

Thank you Jason for taking the time, knowledge, and skill teaching us how to!! I Appreciate!😊

[@Zimgirgaz]

Always love watching a process in development.

[@simnay4612]

Great video, I think Imma try to understand all this better. You have made it easier to learn the smelting process thanks.

[@Alondro77]

Yeah, you always want to put a little excess silver when inquarting. It doesn't hurt the process and compensates if your initial material is higher in gold than estimated.

[@mattbrew7429]

This is great. I found you because I was watching Sreetips videos - and now it's come full circle. Great job.

Jason your works amazing keep it up just love it. I have some interesting ore and projects over in Australia wish I could contact you and share some of my operations. Id love to send some ore over to have tested. Your shaker tables are unreal well done.

[@johannesdesloper8434]

I watch a lot of Sreetips. He usually does 75% x 95% of Silver to keep the inquarted shot in pieces in the Nitric boils and not end up with a Gold powder that is hard to spearate from the liquid. He stirs the inquarted Gold with a carbon rod to get a homogenous alloy. He usually does 5 Nitric boils or so. If you add a drip of Hydrochloric to a small amount of Nitric boil you can check for Silver. Silvernitrate will form white SilverChloride that is insoluable. Very sensitive test. Good luck and be carefull!

[@TravelingThrifter]

That was cool Jason!!

[@devilsdog4334]

If you smash the Cu pipe it works out better than as the pipe just going into the stock pot. Ag and anything else will end up stuck in the pipe becomes a mess to get it back out like that, the thicker you can make the Cu in the form of plate without any openings the better it will cement things out of solution any Au that was taken away by the NO3 in nano particles as a colloidal stuck in suspension will also cement to the Cu and gets caught up in the mess of Ag cementing out and has to be worked again in order to recover it. You did a great job showing how to get started with the process of hydrometallurgy and the mathematical breakdown was easy to understand what you where talking about in the alloys composition. Thank you for the video very useful information and the showing of each deposit type is different and will require you to make some changes as needed for the recovery.

[@marumiyuhime]

when i took chem my chem pro said use more than you need if stoke said 150grams use 200. the target is 6k or less so 3k or 4k will work better than 6k which is the limit. more matrix is better than less. good luck jason. great vids i love what you do.

Hello Jason, love your videos. I've been wondering if anyone has tried melting their gold/silver alloy with lead, then add zinc to gather the silver in the scum that forms on top of molten lead. It seams to me it could purify gold from silver.

[@adamlowe1072]

Can you not heat the corn flakes to make them soft then hammer them to increase surface area further ?

[@cesmith777]

Do you find these options to be lucrative (seems like a big expensive/time consuming process for about $500 worth of silver). Have you settled on any one process that seems to work better for separating out metals? I am interested in potentially opening an E-waste center which would really take any metal producing or recyclable good but be primarily be focused on E-waste due to the precious metals caontained in them.

[@johnh8615]

Silver is a clear when dissolved in acid. So you must do a stannis test to check for silver in solution. Then if negative you go to the next stage.

You need to mix the silver alloy with the cold to get it consistent , also you don’t have to use silver, you could also use copper if you don’t care to recover the metal after the nitric boils
