Refining More Gold Catches

[@jayhac3803]

You are the reason that I'm a hobby refiner now. I found your videos several years ago and it took me time to get to where I could do this as a hobby. But you have encouraged and inspired me to do what I need to do to have a real financial control on my future

[@sreetips]

Gold can really save us

[@anthonyrstrawbridge]

Audio and video were very good but this particular content presented over the top. Sreetips wife brings him gold-seriously! The inquartation principal was well defined and played out well, as well, this viewers observation of the technique has left in him a desire to practice. If I only had someone to bring me some gold. I particularly enjoyed the time lapse of the gold sponge being finely divided into aqua regia. The emphasis of Incremental Dosing Nitric into the boiling aqua regia solution was amazing to view because the time lapse captured perfectly the bits of gold imploding without exploding the solution into a boil over. Removal of the SMB from the high purity gold during the distilled water rinses and Hydrochloric acid rinses presented a very clear solution. The second refining was even clearer. I really liked the end result created by pouring the molten gold under flame into the graphite mold. These presentations are clear and concise and very much appreciated. ✌️♥️👍

I was an Engineer in the Navy. Main Propulsion and supporting equipment. I had the privilege to operate a steam powered turbine that produced 35,000 shaft horse power. Doing emergency Full-Back from full power forward was my favorite exercise. Watching the 1200 psi main steam pressure as I closed the ahead throttle valve and simultaneously opened the astern throttle valve was quite exhilarating. It wasn’t my dream job and I kind of fell into it by default because I’ve always been kind of mechanically inclined. But I’m glad that I did it. For myself, for my family, and for my country.

A small tip. Instead of using distilled water, I have 3 X 10-inch filter housings in series with activated charcoal filters in each housing. This removes ALL the chlorine and removes the need for distilled water. Extremely cost-effective and I'm still getting 5 9's fine gold and silver.

Wow that's incredibly clean gold that's was very informative and interesting ✨️ thank you for sharing the video. 👏👏👏👍👍

[@CrimFerret]

Another great video. You made a great point about inquartation as far as having to dissolve the silver being something you'd have to do anyway if you were going to refine it. If you didn't want to crystalize it out in a silver cell, I'd imagine you could just as easily use the cemented out silver to inquart with more or less just continuously re-using the same silver.

[@sreetips]

That’s not recommended, here’s why; palladium is soluble in nitric acid, the only one of the six sister metals in the platinum group that is. Because of this, using the cement silver over and over to inquart the gold would tend to cause the palladium to build up in the cement silver. Karat gold, especially white gold, is a known carrier of platinum group metals, especially palladium. The Palladium will cement out on the copper with the silver and accumulate in the cement silver. When we finally do decide to run it through the silver cell, then the high concentration of palladium in the cement silver will tend to contaminate the silver cell electrolyte. I can tell when I have palladium in my silver cell because the electrolyte will turn green. If allowed to get high enough concentration then it could begin to plate out with the silver and contaminate the pure silver crystal. The main problem here is not contaminated silver, but rather, palladium is 100 times more valuable than silver.

I personally think why acquire more resources if you have them? Perhaps throw together a pure silver/copper alloy to inquart with? I honestly have no idea, just kinda throwing it out there

Using pure silver to inquart makes no sense. I’d have to run it back through the silver cell again. Step in the wrong direction from the refiners point of view.

Great video sreetips. Question for you sir, if you were to acquire contacts from breakers & electrical switches would you be able to refine them the same way you do the gold & silver?

[@sreetips]

That depends on what other metals are present. Some have tungsten - so I’ve been told. I’ve never done contacts. But tungsten is below copper in the reactivity series so that would need to be taken into consideration. Probably do silver chloride conversion if tungsten is present.

Hello sir, good to see, that inquintation (4.8K - 20 %) instead of inquartation (6K - 25 %) is no big deal, just more silver and nitric used. The gold was in fact about 13.2 K so there is some interval to inquartation that is a bit "forgiving". Good to know. Coud be used in refining when the gold content is not known for sure. Very usefull piece of experience. Thank you.

[@panteleon1]

that dirt in the aqua regia filter is it traces of lead? it should make sense since lead is used in welding

[@sreetips]

Most jewelers know not to use lead solder in jewelry. They use solder chips made of gold with a solder paste that also contains gold. But every now and then someone will try to use soft solder that contains tin and lead to repair a piece of broken jewelry. I’ve been promising to do it a long time, but I’ll get a video out that demonstrates lead removal by adding some lead to the gold then refining it to high purity. Lead, even in trace amounts, ruins the malleability and ductility of the gold. It must be removed before the jeweler can work with it. Adding sulfuric acid and filtering out the lead as lead sulfate will remove 100% of the lead. That’s why I add sulfuric every time I dissolve the gold no matter if I suspect it or not.

[@jackfntwist]

You're a pro at this. Love it. Is there any way to test for lead after the filter phase? I always wonder how well the sulfuric acid works and if it's detectable.

[@disgruntledtoons]

Some of us in the peanut gallery hypothesize that if you are going to do a double refinement of the gold, you can record how much nitric acid is used in the first dissolution, and then see if the same amount or less is required at the second dissolution.

[@apveening]

Same with SMB.

[@sreetips]

Correct, and I do use the first dose to gauge how much to use on the second.

I could calculate a constant for 12k, but since it’s not really used in karat jewelry I’ve never done it. I started with a few beakers from eBay in my back yard twelve years ago. But quickly realized that there’s no way to safely do these reactions without a fume hood.

[@oyekunlesalami7482]

Thanks!

[@PHUCKyoutube689]

With 12k you would add the an equal amount of sterling to 12k to get a 25% or 6 K alloy. Example 100 grams of 12k has 50 grams of gold and 50 grams of base metal so you would just add 100 grams of sterling making the total alloy weight 200 grams, 50 of which would be gold.

[@Skyliner04s]

For the guys who are curious: adding 330g of silver created a 4.8k gold. This error is very much insignificant. sreetips just had to use a little more nitric acid in the end.

[@apveening]

He got lucky, there was no colloidal gold (at least not in visible amounts).

Also how much effort would it take to recycle the red nitric gas condense and bubble through water to turn back into nitric acid?

[@sreetips]

I could pass the inquarted gold through a roller and flatten them out very thin. I could set up an apparatus to direct the fumes into a bubbler and make weak nitric acid. But both of these would add another step to an already lengthy process. I’d rather let the chemicals do the work for me.

I noticed you answer my silver cell silver question again in this for people that missed the comment a while back :) thanks mate! When you did the error with calculations how did that affect it? Did you add too much or too little silver?

[@apveening]

He added too much silver (about 100 g), bringing the alloy to about 20% gold instead of the 25% he wanted (and normally uses). He still was within the margins of error for inquartation (gold purity was a bit better than expected and he added a little less silver than wrongly calculated), so I'd say 22% or 23% as also evidenced by the lack of (visible) colloidal gold. It did not affect the end result.

[@budgiebreder]

@@apveening so all in all it was still ok :)

[@apveening]

@@budgiebreder Yup.

[@sreetips]

I added too much silver. I should have reduced the amount of silver by the amount of non-gold metal in the karat scrap. What saved me: I didn’t add the entire 330g of sterling (I only added 311g of sterling). And I interpolated the karat scrap as 12k (or 50%) when in fact it was higher. These two factors saved me from my careless blunder. I got lucky. The problem could have been thus: adding too much silver will cause the inquarted gold to crumble into a powder, or even worse, form colloidal gold. This would make separating the silver from the gold after the nitric boils a nightmare because I’d have to wait for up to a day after each nitric boil for the gold powder to settle, then carefully draw off the silver solution to get it from the settled gold. I’d have to do this after each nitric boil. I’ve had it happen in the past. I’ve found that it’s better to collect as much of the gold powder after the first nitric boil in a filter paper. Then place in a crucible and melt it into a big button. Test it with acid to determine karat (because it will still contain much silver) and then start all over.

Tap water ice is just fine. Tap water contaminants are measured in parts per million. Not enough to report in a precious metals assay. But, there was an uproar about not using distilled water for the ice. So to appease concern, I now use distilled water for ice. Even though it’s not necessary. But it’s easy and not expensive.

[@ChrisCVW]

So the multiple dilute nitric boils are a boil-over and temperature management measure? Would it be conceivable in a sufficiently large and rugged vessel to just take your estimated yield and calculate a sufficient volume of concentrated acid and do it in one hit or is there some other factor I’m not thinking of? Potential explosive pressures? The acid needs to be dilute to be effective? Just the vessel would need to be ludicrously large and rugged? Allowance for unknown metals in your carat alloy? Something else?

[@sreetips]

No, it’s better and more efficient to use small amounts of hot dilute nitric. Why? Because as the nitric dissolves the silver and base metals, it loses potency and stops penetrating. At that point it’s best to pour off the saturated silver solution and add fresh nitric because fresh dilute nitric has more punch to continue to penetrate the inquarted gold. Using a whole stoichiometric charge of dilute nitric would not change this by much. I’d end up using a great deal more nitric than I would if I use many small nitric as opposed to fewer large nitric boils.

@@sreetips oh that is interesting. Thank you for replying.

@Sreetips I know that you don't do a lot of work with foils and pins, but if I were to take them and inquart them with burnt copper, would using dilute HCL and a little H2SO4 do the same thing as nitric?

Rusty, I’ve never tried anything like that. I don’t know what would happen.

[@rewalston]

@@sreetips thanks, I'll have to try it sometime

[@moviezaftermidnight6348]

Have you tried using a neodymium magnet out of a hard drive to pull up the springs from the molten gold & silver? Like a Mystery Box, you could sell your "exceptional" pieces in the melt pile instead of melting them... calculate how much they are each worth in gold & base on average.. if it doesn't work you have nothing to lose.. Also a couple 2x4 sticks of wood, a piece of drywall and some pink insulation or something could build a small box around the fan box to almost eliminate the noise.. just some thoughts...

Nice setup with the silver

[@VerucaPumpkin]

do you need to clean the crucible to do this? I ask because everything is so sterile and kept separate but it appears to me maybe you use the same crucible which had all the springs waste etc. in it? curious thanks.

[@sreetips]

I’ll use a different crucible to melt the pure gold.

Hi Sreetips i have been a subscriber to your channel for a long time im from the uk is there anything i can use to refine gold i can get from uk chemicals as i think most of the acids are regulated here

[@sreetips]

I can inquart with silver, part with sulfuric (drain cleaner), then refine the gold with muriatic (hydrochloric) acid and grocery store hydrogen peroxide.

Dose that liquid before you add the stump out have a physical noticeable weight to it

[@sreetips]

Yes, it weighs much more than the same volume of lain water.
