poorman's nitric acid

Using poor man's nitric acid to liberate foils from trimmed fingers.

[@reluctantlemming]

Thank you, sir - I love this method! I mean, the idea of reclaiming and refining precious metals with laboratory equipment and chemicals is cool. But doing it with stuff from the local hardware store, garden supply store and thrift stores is badass. This is even cooler than acid-peroxide.

All you have to do is stick a chunk of IRON in the copper solution to make it crash out as copper metal.

[@genewickersham4593]

Yes. Ive used a stainless steel spoon to recover copper from acid solution, but after a while the spoon dissolves. I guess iron is a cheaper alternative.

[@GeoONE]

Yes. Any metal that's more reactive than copper will "cement" the copper from solution. Aluminum is faster but gets hot quickly. Iron is cheaper and slower and doesn't heat up as much.

[@Chewy_GarageBandDad]

Will dye in sulfuric acid complicate your ability to make iron sulfate? Because I have failed at every attempt and doing so. But I've always used a sulfuric acid with a dye in it. NOT really the subject of this video, just side tracked I suppose.

[@leeroy144]

I think that drain opener is only 53-70% concentrated from what I've read online. I have some I'm getting ready to distill and looked it up. Still strong enough for most uses.

[@ryanallen1014]

Depends on what drain opener. Around here we have 97-98% virgin concentrated sulfuric acid for $9.99 a quart. Even if you dont have that concentration and or additives in your acid you can clean it by heating you h2so4 and adding drop wise cold concentrated hydrogen peroxide. Continue heating to steaming off water until you reach the maximum concentration of 98%.

It does work with silver. 100 grams of sodium nitrate and 30 ml's of 98% sulfuric acid and 1000 ml's of distilled water should dissolve 200 grams of sterling.

Usually the white material is tin that is dissolved by the nitric acid that is formed. It is called metastannic acid. Once the foils are gathered, dissolve the foils in what ever acids you like and the white should be left unchanged. Filter the solution well and make sure it's clear before dropping the gold.

Hi there, probably a dumb question, but how much gold fingers did you start with by weight? I think I have the rest of the process down for using the poor mans nitric. Also, as you mentioned the list of other metals this can be used for, for silver recovery and refining this process is ok except distilled water needs to be used, but then the rest of the process is that same right? adding distilled water, and a chunk o copper to cement out the silver? Lastly, cpu pins, kovar, I am guessing this works on that as well? Thanks my friend!

On this particular batch, close to 8 pounds. It will dissolve silver but works better on impure silver such as sterling.

Why do u need sulfuric if ur usng nitrate

[@GeoONE]

The sodium nitrate will not decompose and release NO2 without the sulfuric acid. The sulfuric acid is a catalyst. It decomposes the nitrate salt releasing nitrogen dioxide which is absorbed by the water creating nitric acid in the process. It will not work without the sulfuric acid.

[@adambuysyuckyhouses]

Geo im sorry i dont understand, other ppl do it different or use different nitrate???

[@adambuysyuckyhouses]

Also is heat required for a reaction

[@GeoONE]

The sulfuric acid breaks the bonds between the sodium and the nitrogen releasing nitrogen dioxide. The NO2 is absorbed by the water in solution and is turned into nitric acid all in one go. Yes, heat is required for the reaction to take place.

[@shshgaming189]

Hi Geo so after doing this process and filtering to have just the gold coils how would we dissolve the gold. I thought Nitric acid dissolves gold. Isn't this poormans nitric acid?

[@GeoONE]

Gold foils can be dissolved a couple of ways. Hydrochloric acid and chlorine bleach will dissolve gold foils and powders. Hydrochloric acid and nitric acid will dissolve gold of any type. Nitric acid alone will not dissolve gold. It must be in combination with hydrochloric acid. Aqua regia is a mixture of 3 parts hydrochloric acid and 1 part nitric acid.

Get your money right

[@kallah4999]

There's way easier ways toake nitric acid. Get some calcium nitrate or some other water retning nitrate salt. Then just add sodium bicarbonate, boil it down to supersaturation and let it cool down to room temperature. Collect the sodium nitrate crystals and biol it down some more to crystallize the rest. Edit: it has to be distilled with H2SO4 to get 68% nitric.

[@mihaiilie8808]

Distilation isnt easier than this.

[@ZAPATTUBE]

THAT AIN'T EASY!!

[@RafalScrapper]

very well explained and well showed thanks for sharing cool thank you

[@zee7705]

Hey geo I like what u do I've got something for you. Can sulfuric at the auto parts store cheap it's what they use in batterys thanks I've enjoyed ur video's hope u get this

[@GeoONE]

Yes. 10% battery electrolyte will work.

[@isaacgarza3307]

Can you use ammonium nitrite?

[@GeoONE]

Short answer is, yes. But safety concerns says, no. Ammonia and dissolved precious metals do not react well together and there is a chance of creating an unstable compound.

I bought a drain opener but it says it has lie it doesn't say anything about sulfuric acid

[@GeoONE]

Drain opener was made with both chemicals. You have to find the kind with sulfuric acid.

[@adambuysyuckyhouses]

Geo will it say on the bottle? Isnt lye the opposite of sulfuric acid?

[@GeoONE]

Yes. It will say "contains virgin sulfuric acid" on the label. Yes, sodium hydroxide is a strong base and is the opposite of acid.

[@adambuysyuckyhouses]

Found it thanx

[@GeoONE]

Your welcome.

[@goldentrashdk6851]

Can this poormans nitric be Pre made and stored?

[@GeoONE]

Yes, store in a cool place out of the sun lightly capped. Do not seal completely. It only reacts when there's metal that can be dissolved.

[@goldentrashdk6851]

Geo what would the mix ratio be?

[@GeoONE]

Since I don't premix, it would be hard to say. Solid sodium nitrate equals nitric acid very closely though the needs 1.2 gram to 1 gram of nitric acid. The sulfuric acid is mixed in relation to the water used. I normally mix it 10% concentration roughly. A gallon is 3,785 ml's. A gallon of tech grade nitric acid will dissolve 2.5 pounds of copper. 2.5 pounds is 1,132 grams. It takes 3.3 ml of tech grade nitric acid to dissolve 1 gram of copper metal. 1.2 X 3.3 = 3.9 grams of sodium nitrate to dissolve 1 gram of copper metal.

[@davidlee1719]

in his beaker from what I can see, it is a 16:1:1 (1600 ml of tap water, 100 ml of Sulfuric, and 2x 50ml beakers of Nitrate for 100 "ml" of Nitrate to approximately 800 'ml' of material to be dissolved. Best I could guess.

[@GeoONE]

Correct

[@petrejivan3540]

Nitrat of soda ? Hidroxid of soda? Caustic soda?

[@GeoONE]

Sodium nitrate. Sodium hydroxide. Lye.
