I don't know if it's just me but I could sit and watch you sort scrap jewelry and talk shop for hours. It's cool to see the other side of what you do once in a while.

I really liked this one, the nitric acid boils time lapse was perfect and the SO2 gas precipitation is always a delight to see. And that ingot came out so pretty!!

You should do a video where you do just a few nitric boils, just a single refining, no hydrochloric boils, ect, and do a batch of each like that with a few grams each and send them off to be purity tested to show how much the extra time and steps you take matter. I think it would be a fun experimental video.

Sreetips reserves the Sunday Gotomeeting melt dish for special occasions like the SO2 precipitation. While i like watching the StumpOut method, the SO2 seems to give a ‘cleaner’ result. That bar turned out beautifully

It would be interesting to see the weight difference in the gold at different stages like after inquartation weight, to after the nitric boils weight to final product weight. I know it would waste time with drying it all off several different times but you seem to be a fan of the scientific process and it might shed some new light on how little gold is lost throughout the refining process. I know every new fan asks the same questions because once upon a time i was that fan saying "youre pouring the gold off in your waste container! " haha now i know that Sreetips wastes nothing 😊

I'm guessing the wet weight isn't going to be substantially higher. Gold is twice as heavy as lead and nearly identical to tungsten. And not only that if it is precipitated under the same conditions will probably always have a similar wet vs dry weight after decanting.

I would love for you to talk about the differences in the types of acids used in your videos. The strength comparisons and any other details that are relevant would be appreciated. Also discussion about the weight of the gold versus other material when rinsing and pouring off the waste. It sometimes seems that you would be pouring out the gold but I assume it is not suspended and that it is other stuff that is poured into the waste container. Of course I know that some does and you will process it later but I think it would be good information to include. I’m sure you feel like you are always repeating the same things so that might be something new for you to talk about. I love going on KZread and seeing that you have posted a new video!

Hello. After looking at thousands of pieces of jewelry over the years, it’s possible to distinguish real gold from “fake gold” with just a glance. This comes from experience. There’s no substitute for experience. The acid test can be used to determine the purity of the gold as well.

That was one of your best pours I've ever seen BTW. Nice job!

Nice job Mr S. Just a thought for you... here in Philippines HNO3 is very expensive, so what we do is collect the NO2 (evolved during the process-red fumes) using a vacuum adapter into a condenser (liebig) at 5C and then from there into a gas trap (in Ice water), with some H2O2, this produces very little, if any fumes as all of the NOx is converted back to Nitric acid to save money, also this has the advantage of not rusting up any metal (in the fume hood- stands brackets, etc) from the NOx vapours. Would make an interesting Video, but you may need a larger fume hood to locate the glassware.😊 All the best

Very nice. Gold chemistry really is facinating. As an undergraduate, I made a lot of batches of colloidal gold from Aldrich's Hydrogen tertrachloroaurate. I worked with a bunch of post-docs in Michael J. Natan's group at Penn State doing a lot of surface chemistry. Got my name on a few papers outta the deal. Seeing those acids reminded me of always cleaning our glassware with aqua regia and pirhana. Well, no piranha on the glass substrates (we used microscopes slides). It etches the glass and would aggregate the gold colloid...defeating the whole purpose of making the colloid in the first place :)

Goal achieved. Well done! Wow...

Wow!! Very impressed! I hate to bug you with dumb questions but I need to! I was given a small container filled with ingots. It is obvious most of them have good amounts of gold in them with what looks like mostly copper. Some are a rose gold mix of the two while others have distinct Sections of what is obviously copper and distinct sections of much brighter/ higher karat gold! So far I have sat them in a mixture of 2 parts muratic acid to one part hydrogen peroxide and some heat. I kept the heat between 80/110 degrees F. I let them soak until the reaction fazed out. Pulled them out and rinsed them with water and baking soda to neutralize the acid leftover. Ok I should say this is my first time ever attempting those abs to be honest I had no idea what was going to happen. I understand that the process to do it the right way a lot more entailed, and requires a lot of knowledge and probably experience like you have sir. To my surprise, though all of the pieces have shrunk down quite a bit and the sections of gold in these ingots are much larger and more defined, and very very bright gold. Which appear to be a high carat. I am still not separated completely from the copper. My question to you is am I royally messing this up? Also, in theory, could I continue to do the same process and get rid of all the copper, and be left with the gold, that is in them? Again, I am very new to this, and would appreciate any knowledge that you can pass down. If you know of a way that I can accomplish, pulling the gold out of these ingots with minimal expertise and equipment, would you please enlighten me? I am very much thankful for your time!

@OP - it really shows you what the nitric acid is doing. It's not the nitrogen, so much, it's the oxidizing power of the nitric acid that's really doing the work. A strong oxidizer makes the gold actually able to react with other things, kind of like a catalyst. Even though gold won't form an oxide on its own, the oxygen kind of "pulls" on the atoms just enough to convince them to bind to something else like chlorine, one of the most reactive electro-negative elements. Flourine would probably work even better, except that HF is so deadly no one wants to work with it (and it dissolves glass). I think Periodic Videos did a video on aqua regia explaining it more scientifically.

Sreet, I was doing a gold refine and had some HCl gold poured off with some SMB in it that I had forgotten. I was running low on HCl, so I used it in the boil-down to get rid of some excess nitric. Just before it went in syrup, I noticed clumps of brown stuff beginning to gather together and had no clue what it could be. Then it hit me that the pour-off I used had SMB in it. I let it boil for several minutes and then added pure HCl, thinking it would dissolve, but it didn't. When I filtered it off, I could tell it was gold in the filter. I tested the liquid for gold, and it was negative, so it had all formed during the boil-off. Have you ever had this happen, and was I just lucky I didn't screw something up!
