[@roberthayward9299]

Thanks once more for a great video. As someone with a background in formal chemistry, I find your comments about difficulty dissolving the last of the gold with hydrogen peroxide really interesting. There are a few competing reactions when you add hydrogen peroxide to a mixture of gold and hydrochloric acid. The hydrogen peroxide will be oxidising chloride ions to free chlorine and this chlorine in turn, will be oxidising the gold. The less the gold in the mixture, the longer this process will take. However the hydrogen peroxide will also be decomposing to oxygen gas and water. This process is quite rapid as can be seen by the foaming of the mixture. When there is very little solid gold left, the hydrogen peroxide will largely decompose before there is enough free chlorine to react with the gold.

i think some of that junk could be from the ice cubes, i learned from videos about making clear ice that the air bubbles in the ice cube are created as the cube freezes from outside in, the ice on the outside of the cube is clear because its pure, but as the cube freezes it forces impurities into the center of the cube, creating the bubbles

Awesome recovery from those gold waste containers - it would be really interesting to know how much gold you refined to create the waste and calculate something like the loss rate per gram of refined gold. I imagine it's quite low. Great video! 👍

[@sreetips]

I usually pour off gold during the rinses. I could minimize this by waiting for the gold to settle between each rinse before pouring it off. But this would greatly increase the amount of time.

[@fredrichardson9761]

@@sreetips I suspect your loss is really low though. For example, if you refined something like 40 toz, your loss would be well under 1% and you eventually recovered it anyway.

It probably has tiny invisible air bubbles that causes it to float. Gold is about 19 times heavier than water so it should not be able to float on water.

[@ChrisCVW]

A serious one today. I see that first pour off of the waste solution after precipitation often looks like it has particles floating on the surface tension. Is that how some of the precipitated gold gets into the waste collection? If so, I see the prospecting guys use detergent for this problem for flour-gold. Would that mess with your chemistry at that stage?

[@sreetips]

Yes and yes.

[@deshazo_henry]

I have a crazy question? Stannis chloride is tin chloride I think. In the presence of gold it turns black. Find a long time ago that if you rub a gold ring across a woman's face who's wearing makeup you'll get a black line. I wonder if foundation or the base makeup women use has tin chloride in it?

[@marinoceccotti9155]

The final waste will always be a concern for me. Once all the copper has cemented, I guess all is left is an iron compound like iron sulfite (?) most certainly contaminated with other metals (lead, zinc, tin, nickel, rhodium, manganese, tungsten, etc.). How do you dispose of it?

[@Reasonist]

Check out his early waste bucket treatment videos, he shows the process to bring the wastewater to a neutral and disposable state 🤙🏼

[@sreetips]

All the metals in your list (except magnesium and zinc) are below iron in the reactivity series. They will cement out as metals along with the copper. The acidic iron solution is dropped with sodium hydroxide. The dehydrated metal hydroxides are thrown away. The caustic liquid is adjusted to pH 7 with swim pool decreaser and added to the normal waste stream. Nothing acidic or toxic gets poured down the drain.

[@apveening]

At the start I expected you to use nitric first to get rid of other metals than Au and maybe Pt.

[@glOckcOma]

Would it be possible to soak the test strips in the stannis solution, and have them dried and used later. Would they still turn black if dipped in a gold bearing solution? Just a thought. Edit: I guess it could contaminate the gold bearing solution, so maybe not such a good idea.

[@NOFX0890]

Thats a really cool idea. It does expire, but it would be very interesting to see if it worked immediately after drying. Edit... Maybe dropping the solution onto the test strip, rather than a dip.

[@briankirk1969]

Interesting idea, but not possible. The stannous chloride solution is made up from stannous chloride crystals, water, HCI, and tin (as a preservative). That solution dried out wouldn't have the same reaction.

Yes, iron will cement everything below it in the reactivity series.

[@SURFEAMORETERNO]

​@@sreetips thank you for reply. I have some cell phone pins and springs, and I intend to dissolve everything in aqua regia, and then add sulfuric acid to try to precipitate the gold. If it works, I try to treat the precipitate with a solution of oxalic acid, to eliminate the iron. I don't know if it will work, but it will be interesting to do. A big hug.

[@sreetips]

@@SURFEAMORETERNO You sound exactly like me when I tired to refine my first batch. Here’s what the pros told me: “please let me save you the trouble. If you dissolve everything in aqua regia, then you’ll just end up with a big toxic mess and no gold.” I don’t have any experience with cell phone pins and springs. But I do know that sulfuric acid won’t precipitate gold.

[@SURFEAMORETERNO]

​@@sreetips Thank you for your collaboration. I always find people who help me, maybe because I help people too. I have little ferrous plated stuff, and I would do it just to see the result, after watching your video. I was believing that sulfuric acid could form ferrous sulfate, with the iron present in aqua regia. I don't know how to recover gold from this kind of scrap metal. Perhaps mercury would be an alternative? I dont know,and due to toxicity is needed to have a distiller. So it's best to keep raking it in for now. Thanks buddy.

[@brett76544]

I still think, its just from waste. I can remember doing some testing for a sewer system for an industrial waste water permit for a college, I was finding huge amounts of copper. The funny thing the building that was causing it was not the labs or the filter system for the dental training area, no it was the HVAC drain units and all the copper drainpipes that were reacting to the condensate that they drained away.

[@sreetips]

All the copper pipes in my house eroded over thirty years and began leaking so I had them replaced with pvc. Copper does get in the drinking water from copper pipes.

[@brett76544]

@@sreetips The pipes had accelerated corrosion from draining into mop sinks, and one floor drain. If they drained into the plumbing system, they would not have had as much corrosion due to the air getting in. Now the labs had glass drains to the treatment system that a few years later failed spectacularly or blew up. One of two times I ever got into a Class A protection. Yellow bubble suit with O2 tank. The other was an abandoned Crome plating operation and some of the waste chemicals in plastic barrels had reactions producing gas since they were not cleaned out of the previous chemical before filling.

[@erbalumkan369]

Hi Sreetips. Usually i see you add a few ml of sulfuric acid to precipitate any traces of lead. I know in some gold solder there is cadmium. Will the sulfuric acid precipitate that as well? What about tin?

I wish I was closer to where you live. I'm sure you're nowhere near Southwest Washington anyways. At the farm I used to work at we had a copper sulfate additive for the water. We had buckets of 16 ounce packets of "acidified copper sulfate". It's copper sulfate mixed with citric acid. I do copper and aluminum bronze casting. So I put some of that copper sulfate in some buckets of water and threw some pieces of iron in there. Melted down the copper and used it for casting. If we were close to each other I'd be more than happy to pay you forty bucks for that scrap copper. Your trash is my treasure in this case haha.

[@OneOfDisease]

Could you melt the copper and then use it again for cementing other precious metals vs. throwing away and buying new? Or would that process take too much effort? I guess you would have to roll it flat or somehow pour it into sheets, and the contamination would be a factor.

[@sreetips]

Correct

[@slimpickins09er87]

You shouldn't try to recover the copper to .999 fine. You should just sand cast plates with it to use in the stock pot. Plates as in commercial grade grounding plates, not as dishes. Maybe even miniature cricket bats or boat oars so you would have a good bit of surface area and would be able to stir with it as well. Do you think you needed more hydrochloric acid to get that last bit of gold to dissolve? That the solution was already saturated with the gold that had been disolved.

[@sreetips]

No, it’s because the H2O2 decomposes to water and oxygen so fast that it don’t have enough time to get at that tiny amount of gold that remains. A chemist told me this.

Technically speaking, wouldn't the gold actually be at least quadruple refined since it came from being poured off a previous refining? And some of the gold may have came off a 2nd or 3rd refining too so some of it could be quintuple or sextuple refined.

[@sreetips]

Technically, yes

[@anthonyrstrawbridge]

I found the workflow most interesting when the aqua regia precious metal solution dropped the pure au with the addition of 100 ml Feso4 allowing the PGM to be poured off into the soup pot because the following procedure of placing the highly pure au into a suspension of hydrochloric acid liquid + H2O2 challenged me with little question(s) regarding the undissolved highly pure au which was later placed into the stock pot along with the HCL+H2SO4+H2O2+Na₂S₂O₅. So why did Mr. Sreetips choose this workflow and why did he dump the highly pure au into the Stockpot soup? I assume he is cooking up - another recipe.

[@sreetips]

As the gold dissolves, the H2O2 decomposes to water and O2 so rapidly that it don’t have time to react with that tiny amount of gold. The small the mass of remaining gold gets, the more H2O2 it will take. This is what I’ve been told by those with more chemistry knowledge.
