Might be interesting if you start with a fresh jar of gold refining waste and track how many grams "shy" you are with each batch, then recover the gold from the waste jar and compare numbers. Did you miscalculate? Did you lose some somewhere? Or did it just get poured off into the gold refining waste jar and not make it to the melt dish.

Yeah I don't know why he doesn't attribute that to his jar, he has already said it is his "savings" jar, or I guess when refining the jewellers trimmings (Sree)"Tips" jar 🙂

Funny, I took my girlfriend to an estate sale last weekend and we followed the get there early rule that you always remind us of. As I was looking at something near the entrance of the living room, she zoomed in on the corner of the dining room, on the other side of the house, where the "gold" was. Ok so we just about cleaned them out of gold and the silver set, I have 6 nieces that would just love to have more jewelry. After getting home I put the fly making light with magnifying glass on the table and we were reading and separating out the different pieces and calculating just how much gold we got. The look on her face when I said the weights and total monetary worth between the plated, gold filed, and karat gold was price less. Most of the jewelry was in bags as costume jewelry for 5 buck. Then I started to think about what you said about a woman that can spot gold like that. Still that date ranks up there with the raspberry picking and jam making date.

Copper can be used, but because it’s reaction with nitric acid is a 2 electron transfer rather than 1 electron, as is the case for silver, it takes 2x the amount of nitric acid to dissolve away the copper and get the gold. Typically, nitric acid is one of the more expensive reagents in refining, even moreso than the cost difference between copper and silver metal, so silver is preferred

[@sreetips]

Not only that, I refine silver also. So for me, using sterling silver is a much better choice.

[@spiderdude2099]

I’ve watched quite a few of your videos like this one and it still blows me away. The way you can (in dum dum terms) boil up silver and gold and refine it to such a purity is super cool.

I would love to buy some of the stones you remove from the gold. I checked your ebay site and none were listed. You still rock thought!

[@jackmclane1826]

Only drawback is copper consumes more 2 nitric acid molecules instead of silvers 1. And if you also refine sterling silver to silver... dissolving it in Nitric is basicly the standard first step. So you can make double use out of step, hitting 2 poor birds with one bottle of nitric. ;)

[@5t0n3d-G4m3r]

hey Mr. SreeTips have you tried preheating your mold with the oxy/ast torch to see it it affects the finish of the bars it forms?.... seems like it should likely make a cleaner surface finish on the bars if the casting apparatus was at a closer temp to the metals themselves being poured into them

1. Hi sreetips~ How do you configure the proportion of aqua regia? How to calculate the ratio of hydrochloric acid and nitric acid? Looking forward to your answer. Thank you.😊 2. Also, you used to use hydrochloric acid for rehydration. Why do you use ice cubes now? What is the difference between using ice cubes and using hydrochloric acid?

[@sreetips]

1. In my experience, I can dissolve an ounce of gold in 150ml hydrochloric acid and 15ml to 18ml nitric acid. Roughly ten to one, hydrochloric to nitric. The old 3:1 or 4:1 HCl/nitric is antiquated. That would be way too much nitric, wasting chemicals, and guarantees problems during precipitation. 2. The only reason I used water instead of HCl this time was because I used ice to cool the solution and dilute it. I don’t think it matters whether HCl or water is used. The main reason for dehydrating is to drive off excess nitric.

[@user-cm9ok3dv2e]

@@sreetips Every time I hear your answers, I benefit a lot. Thank you very much.👍😊🫡

[@Vibe77Guy]

The point of inquaurtation is to keep the gold from being able to form base metal inclusions and protecting those inclusions from the dissolving agents. I have been using a sodium chloride brine electrolysis cell to isolate tin from plated phosphor bronze granules base metal. The result is a very fine grained mud that is very easy to wash in dilute sulphuric acid and dissolve just the tin out of the process. The remaining tin free mud is then processed in a copper sulphate electrolysis parting cell. I'm not sure how silver would react in the sodium chloride brine electrolysis, but I don't think it would passivate. Gold forms gold chloride, for just an instant before the sodium snatches the chloride ions back, same with copper and every other constituent metal in the alloy. I then use a 3 gallon beer brewing funnel as a seperatory settling tank that collects the mud in a mason jar at the bottom. This method uses no harse chemicals in reducing the metal to fine powder, and generates very little in the way of fumes, though there is some hydrogen given off. The brine is eventually converted into sodium hypochlorite, but a little H2O2 converts it back to brine, and an excess of salt crystals maintains the concentration. If another idea works out, ill be able to separate the gold from the copper without chemicals as well.

[@sreetips]

Nice!

[@Vibe77Guy]

@@sreetips I'm attempting to set up an apparatus for separation of gold from copper using the differences in density and magnetic susceptibility by allowing the "muddy water" from the brine electrolysis to drift down into, and along, a slanted magnetic field. The copper should be affected much more than the gold, allowing each to collect at different locations at the bottom of the separator. At the very least this should sharply reduce the amount of refining chemicals required.

Copper does work very well to inquirt your karat gold. You can use sulfuric acid or copper sulfate and make a popsicle and use electricity to grab the copper and nickel. Noble metals stay in the Anode's filter slime. Saves on nitric acid use.

[@sreetips]

For me the copper seemed to work better than silver. The gold came out cleaner than using sterling to inquart. Less silver chloride present.

[@christopherleubner6633]

​@sreetips copper works better because ir is more reactive, and more of it per molar mass. The result is the particle size after acid or electrolysis is extremely fine compared to that using silver.

Wow! That was quick and sweet inquarting low Karat gold with copper. With your 26:21 acids and stuff getting over $5,700.00 USD ($4,900.00 USD a year ago) now in gold is great. Gold going higher is going to reward your time and efforts now.

[@sreetips]

Not to be contrarian, but gold has not gone higher. Gold doesn’t change, it’s stable. It only appears to have gone up in value. But what’s really happened is the currency that gold is priced in (US dollars) has declined by so much that it takes a lot more of it to equal a single ounce of gold. It’s the value of the currency declining that makes gold look like it’s going up in value. Gold is the same as it’s always been and doesn’t change. Once you understand this concept then you’ll be able to understand why it’s important to hold hard earned savings in gold, rather than holding savings in paper currency that can be printed “without limit” out of thin air. The currency number assigned to gold is a good measuring stick for us to see how much value the currency has actually lost.

The biggest difference that I found is that copper takes over three times the amount of nitric acid to dissolve than silver. It’s worthwhile if you don’t have silver, but if you have silver to inquart it’s a much more efficient use of resources. The silver is recovered. Nitric is consumed.

[@ZoonCrypticon]

Thank you very much! A question: couldn´t you have started the process after the copper inquartation with the much cheaper sulfuric acid, so that the bulk of copper ions would get washed out quite quickly, due to its high solubility in H2O and on the last step make a boil with nitiric acid, to get the silver out, as it has a better solubility in its nitrated solution?

You then moved to distilled water ice cubes because of the chlorine. I’m just getting my feet wet and had a question about this. I have a well and a water softener that we Iron Out in . Would either of those necessitate me needing to use distilled water for my gold recovery projects? I can bypass the water filter by getting water from my outdoor spicket as well. I’m in Central Indiana and are well. water is known for a high iron content. Thanks!

I use tap water for my ice. Contaminants in parts per million. Not enough to report in an assay.

Another excellent video, would you say well water or spring water is as ok to use instead of distilled, as long as it's not treated? Is it just the city water that has chlorine

I’ve never use well water. I always use distilled water.
