I always love spotting the secondary precipitations in the waste container. It's like an Easter egg.

Start to finish is always my favorite, especially when you throw something different in! Really liked seeing the direct results of the lead precipitation, it's like something you know is there but normally not nearly as pronounced! Excellent and educational, tip of the hat to you sir!

Now that I’ve looked at it, it does look exceptional.

Your work is soooo fascinating. I have learned an enormous amount of practical knowledge on a subject that I simply can’t get enough of. Thank you so much for sharing Mr. Sreetips. You do such great work and your respect for the subject matter and your audience comes through in every video.

I'm so impressed with you're videos, also that you go through all the comments.

Great video! Love your relaxed but enthusiastic way of talking us through the process. Wonderful how i can still keep watching gold refining video and not get bored of it!

I loved actually seeing the lead sulfate this time. Cheers, sir.

I thought that was keif in the thumbnail being lit by the torch 😂😂

Excellent work as always. This electrolysis stuff is very interesting. I've been reading my new CM Hoke book this weekend. Fascinating.

That’s an amazing process sir thank you for all your hard work time and money you spend on these experiments you show us week after week year after year!

The next run you do with the karat scrap electrolytic Gold cell is love to see the gold from the titanium under a microscope😏👀👀👀

I got into making jewelry in part because of you. Of course now I can recycle the failures using you as a reference to remember all the stuff I learned.

One of my favorites. Even though you had mistakes you didn’t edit them out. Thumbs up 👍🏾

Always amazed at how professional you are at recovering precious metals. I am not so inclined to do this myself as i am no chemist by any means.

I never get tired of watching gold melt! 🔥👑🔥👈😎👍

You are always welcome. Those who have opted out are really missing out. Great rapid-fire production! Thank you Sir!👍👍🤟

First lead precipitation from H2SO4 I've seen on your channel Sreetips. I know you always put it in just in case but this is really cool because of the material you put in, the odds of precipitating lead was virtually 100%. That's really cool to see in action.

I think I’ve been watching your channel for about 200 years, but this is the first time I remember ever seeing lead precipitate out after sulphuric acid treatment, even though you do it at every gold refining!

That’s because I actually seen some lead solder on some of the karat scrap in this lot.

Every time you make a bar of 9999 gold I just love it, its beautiful.

Really cool experiment SReetips. Best gold purification on the 'tube!

I have to agree the time lapse is crazy the gold looks like it turns into a crystal

Melting in a crucible with an electric coil around it could also be spectacular in its own way. Maybe it can reach even higher temperatures, so that it cools slower, and the bottom and sides of final bar could be smoother.

Thanks for taking us on these experiment journeys with you. It is obvious this is horribly inefficient, but the results look fascinating. Always something to learn.

Actually, just about all pure gold bars or coins are refined like this, only on a much larger scale.

This was very interesting to watch as always. The time lapse of the electrolytic process was awesome.

Good seeing the various approaches. Always interesting. Going forward I suggest you keep the DC power source out of the fume hood. Some of the acid vapours which turn up in that area will destroy electronics. Al alternate approach would be flexible heavy duty leads (similar to what you find in jumper leads of the middle quality) to carry the current and not fight your positioning too much.

Awesome video nice gold bar and sharks tooth thanks for sharing sreetips

First 👍's up sreetips thank you for sharing 🤗

It would be interesting to see the resulting crystalline structure on the "Shark's Tooth" if you allowed the bar to solidify slower, giving a larger crystal structure. And an electrical tip for you - It is the current that is the important variable when electroplating. The higher the current, the faster the process. A lower current will give a more polished/plated finish while a higher current gives the result you have. The current is determined by the voltage and resistance of the circuit, and the resistance is determined by the conductivity of the solution and the distance separating the electrodes. So the standard process is to set your system up, turn current all the way down, and voltage all the way up. Then turn the current dial up to the current you want. (In your case, 9A is what you have been running at) This will adjust the voltage as the solution changes to make sure you stay at the required current.

@sreetips

24 күн бұрын

For refining, the opposite is true. Constant voltage is what the book calls for. Let the amps fall where they may. Variable voltage could cause other metals to deposit, if present in the electrolyte.

@MickTee2k

23 күн бұрын

​@@sreetips I believe voltages are specified in most texts as it is one of the primary variables that is easily measured. There is a document online that states: "The voltage and current that must be applied to a cell for most efficient gold recovery depends on a number of factors including eluate conductivity, pH, temperature and the concentration of all the different species in solution. At SDGM a cell voltage of around 3.5V is applied for optimum gold recovery." It then goes into more detail: "The rate of gold deposition increases with increasing current, up to a limiting amount, at which point the maximum cell current efficiency is obtained. Above this point the current is consumed by other side reactions such as the evolution of hydrogen and the deposition of other metals such as copper, and does not contribute to further gold deposition. The required amperage is determined by the plant metallurgists and entered into Citect as a control set point. The output of the rectifiers is maintained at the set point by a control loop. The optimum amperage is somewhere in the range of 30 to 50 amps per cathode." Note that they state "We use this voltage", but further explain "...because it is the voltage that gives us the current we want." But this was just a FYI - if what you are doing works for you, then keep doing it. But understanding the process allows you to improve it. The document implies that 40A is their optimal current, which may allow you to speed up your process. (And I am by no means an expert in this field, I just understand electricity and trying to understand metallurgy and chemistry) The full document can be found here: rsteyn.wordpress.com/wp-content/uploads/2010/07/electrowinning-and-smelting-basics.pdf

I think a highly polished plate of pure chromium would make a better cathode. A mild steel spatula is not going to scratch chromium, and the highly polished surface should aid in releasing the gold deposit.

@JP-kb5ng

24 күн бұрын

I think reversing the polarity of the cell for like 1 second would cause all the gold to pop off. But he'd probably want to do that in a different batch (or type) of electrolyte, so that would add another step/hassle. He might also try putting the cathode in the freezer overnight, the contraction caused by lower temps might cause the gold crystals to fall off.

I have nothing negative to give, we have opposition in all things. When you do good you will draw some negative. Keep up the good work please 😃

It is better to create the cathode with 1000 purity graphite bar. They can be cut with diamond discs so there is no possibility of contamination of the lower alloy. I use a flat bar and modified the ingot part so that the gravitation bar is half the height of the ingot plus a square on the bar to avoid spilling the casting. I also suggest that you apply electroplating to the crocodile clips to prevent corrosion of the metal with rhodium or platinum plus a heat shrinkable sleeve to protect the visible area of ​​the copper. Also the soldering part of the clamp to copper can be insulated with silicone without sections so that corrosion does not get inside the main cables. Another method I use is a perforated crucible and add there is the shot the graphite is never damaged in the electrolytic acid for massive electroplating

Be sure to do reactions in a fume hood. I ignored this and did reactions in my back yard. The fumes will get in your lungs, hair, clothes, eyes and skin. So that now I suffer reduced lung function and blurry spots on my eyes from the nitric fumes. No way to safely do these reactions without a fume hood. The concentrated red gas (nitrogen dioxide) forms nitric acid in contact with moist body tissue.

@sreetips I may get a full body suit, or pajamas from the thrift store. Hat, scarf, mask and goggles. And after, just put the stuff in a bag and throw it out. And not even breath at all while I'm near it.

Just for purchasing I know I'm always drawn to 5g or 10g bars as the price is more aligned with "middle class" etc. Just so people understand what they are looking at 91.4g x $74.83 (6/2/2024) = $6839.46 (roughly as prices always change) 100g bars are showing $7732 ish currently

You could almost hear the collective “OOHHHHH” of the viewers when that gold sponge splashed out of the funnel😅 Suggestion for Sreetips: Find a worn out cheap bar mold and grind a hook shaped channel at one end with a dremel tool. Pour the bar and hook as one flat piece. Once cooled, twist the hook 90deg to hook onto the beaker.
