@@davebryant8050 The faster it dissolves a can tab, the easier it will clean concrete. Based on this video, the Muriatic will work better than the other. Yes, go ahead and buy different grades of acid and compare, have fun. Make a video.

@@Wintrycomet757 Thanks I guess. Have a good life.

@@occamsrazor9183 thanks man...

What makes you think I am dishonest exactly?

Yes I did! Thanks a lot. I actually used some in the gold refining video.

The muriatic acid will dissolve the iron and leave the gold. It will take a long time though. Heating the acid while it dissolves will speed things up, but be careful of fumes. You may try to mechanically remove as much of the mold as possible with an angle grinder, bench grinder, or whatever you have first. Sorry the link is dead; I will try to update it soon.

Oh, and next time use a graphite mold. If it sticks you can bust it off. Thanks again!!

@@IIIKNOW3 Oh 4 sure on that note graphite 4 sure, I used this steel one for silver rod and it worked perfect but with gold a different story, tomorrow I am going to melt gold and just get it liquid in the dish and then shortly after that pull out the disc/slug with pliers as I do not have a graphite mold yet

LazerSteve is a very smart man. I have learned a lot from him. His recipe is probably more chemically balanced by stoichiometry than what is in the video I made. This acid has residual sulfuric in it which is bad if you need to make lead nitrate or I have been told barium nitrate also. It doesn't hurt anything if you are using it for copper, silver or in Aqua regia for gold; in fact, it is helpful to remove any lead that may be in your material like from solder. This was given to me by someone years ago, and I don't even remember the guy's name. I only made this video to show what helped me get access to nitric when I couldn't purchase it.

@@IIIKNOW3 Yes, it works great on dissolving base metals leaving gold foils, and aqua regia. I would've been without had you not posted this video.

You are welcome!!

I live in Florida. So I paid about $145 for 2.5 Liters delivered, so more like $58/L I spaced on the half liter LOL. I know I could find better pricing, especially if I bought more quantity. Where is your source? Next time I would be willing to buy 10L at $20 each. If you try this, know there is extra sulfuric that will be unreacted which won't hurt if you are working with copper, silver, gold and the likes. Thanks!

Duda energy

Thanks, I will try them next time.

You are correct. Also an aqueous sodium hydroxide solution will make a blue solid precipitate. Thanks for the view and the comment. Have a great day.

I heard good things about the JSP brand of Fluorspar that I used in this video, so I tried it here as a thinner. The Borax is just 20 Mule Team, which is not the anhydrous kind, but I have never had any issues. The Potassium Nitrate is Spectracide Stump Remover that is always very pure stuff. The Silica is just a crushed-up quartz melt dish (trying to recycle) which may contain some other trace metals from its uses. At this point I was only focusing on getting rid of that magnetic stuff. By the end of this one, I could just part with acid because of the high silver content, but I want to do one more just sticking to the flux and fire to see how far I can go before having to switch to acids. I would actually like to switch to a cupellation, but I don't want to use lead and I haven't done one with bismuth yet. As always, I appreciate you. Go find more "dragon stones" LOL love your vids too!!

Don't we all screw-up sometimes LOL!!

My first question would be about the copper. Is the copper clean and bright, or old stuff, like soldered in places?

You could be correct about press and seal, but I don't know. The do sell PTFE cap liners on Amazon in various sizes although a bit pricey. I have found that using metal caps/lids will corrode over time with even a liner. HDPE is fairly resistant to Nitric, unless you have the 95%+ fuming type stuff. If you plan to make this, you should also plan for only short-term storage anyway. Thanks for the comment and the view!!

​@@IIIKNOW3mine didn't turn out as well as yours it was a little weak but I'll try again when I can afford to take another shot at it I'm on a virtually non-existent budget so I have to be patient but that gives me more time to strip phones and laptops and various other assorted electronic devices but I'll eventually get there. I might have done something wrong because I had a lot of potassium sulfate Crystal's left as a by product so I don't think I got a very efficient run out of it. I would love a more efficient process without so much leftovers I can't do much with if you happen to know of any that don't require distillation

Well, I appreciate the conversation. What I did to be more efficient and have less waste was to purchase 70% premade stuff. The downside is the cost at around $75 per quart. This was the best way I found to make a workable Nitric for a lot less money and without distillation. There are other ways, but they all have downsides. Sometimes the crystals form differently, even trapping good HNO3 inside them. I would recommend trying several times to see if you can get better results with practice. What I did sometimes was to pour off what I could at first and use that as the higher concentration, then wash the crystals in distilled water and save that when a lesser is acceptable. Can I ask what methods you are using and which parts you are trying to process and what metals you hope to recover?

I have heard it makes an excellent fertilizer, potassium, sulfur, go figure right? You probably want to check what your plants prefer before applying. I have bags of the stuff just in case I find a need. It seems like it could also be used in a flux recipe to convert base metals like iron and copper into sulfides for removal from precious metals in a furnace. Maybe I will test that one day also LOL. Currently I am working on something like that for gold plated scrap, and it could also work in refining computer or electronic wastes.

Oh, also make sure it is rinsed very, very well, in case that is not common sense. LOL

Thanks

Thanks!!!

You are welcome!

You are welcome

I purchased a distillation set so fuming should not be difficult. For my purposes, working with metals especially silver and gold, there is no need to go above 70% and in most applications even that will be diluted or mixed with Hydrochloric for Aqua Regia. I actually purchased 2.5 liters of premade Nitric at 68-70% to make my life easier but it is very expensive. This video is just how I made mine to use for silver when I didn't have the funds to get premade, so I thought I would share for someone who is now where I was then. There is such a small margin in small batch precious metal refining if you have to purchase the source material then buying nitric is too expensive. An example would be if you bought a bunch of silver plated stuff and thought you would dissolve the whole batch in Nitric to recover silver and copper; then your acid expense would be about 2000% or more of the metal value recovered. Thanks for watching and the comment!!

​@IIIKNOW3 Yes, I suspect that there are some better electro chemical methods to recover precious metals than the very heavily chemical based methods being commonly used on yt

Yeah, pouring the acid into the aqueous solution has caused violent eruptions and burnt my skin. You watched the video, there was no splash or anything dangerous. Just because you learned something in a book that is usually what happens, does not always mean that it applies to all situations. I know this from my experience and my previous mistake that actually caused me minor pain, and it could have been worse. Please know what advice you are giving. Go back and watch it again and post the time where this violent reaction happened. Thanks for watching and the misinformed comment.

And it is POUR not POOR

Be smart and learn to use the proper verb if you are going to criticize someone else's work.

I did thank you.

Thanks for the comment. I recently purchased 2.5 Liters of 68-70% Nitric for about $145 after shipping and all. It takes quite a bit of it to dissolve Sterling Silver. I use it for Gold, but it is too expensive to use for refining Silver unless the Silver is FREE! You can use this acid for Silver and Copper, no problem and save big $. I even did a video using the last of this batch to refine some gold about a month ago. It is not perfect and it does contain some left over sulfur, but that won't hurt anything when using on Copper or less reactive metals like Silver and Gold. In fact, it will drop any Lead out as white Lead Sulfate. Have a great Christmas holiday season. Be careful and good luck!!

@@IIIKNOW3 I reused the copper nitrate by removing the copper w/ electrolysis . I was able to cement Sterling bypassing the disolving and Cementation route . Look forward to making nitric for my next cell thanks again

Do mind if I clear something up ? To make poor man’s nitric Do you have to add water , can the KNO3 just be added to H2SO4 , then freeze the copper sulfate crystals out .

Ps Lazer Steve straightened me out with removing the copper from copper nitrate ( thanks LS)

@@Hill-13 It has been suggested to leave out the water, and some have told me they never use H2O. You don't need water if you are going to use distillation with the KNO3 and H2SO4, and the results will be better although more work. I was going to try the poor man's, freezing without water but haven't had the time yet. This video is how I made it with the best results over the years. If you plan to use this method regularly, try adjusting the ingredients until you find the best for you. I just found out the hardware store near me discontinued stocking the Spectracide Stump Remover. That is disappointing because I was working on a flux recipe containing KNO3 as an oxidizer and I am almost out. Let me know what happens when you try no water.
