Refining chemicals: suppliers

[Lou]

Here is a list which was made by a member of the sciencemadness.org forum. It is more for amateur chemists, but many of the chemicals have a great use in precious metals reclamation and refining.

Here is the link; thanks should go to he who took the time to compile this list, Chris Benton.

For us, inorganic chemicals list will be the most useful.


I'm guessing that we'll probably want to sticky this one.

Does anyone have a source for gallon+ jugs of hydrogen peroxide?

 

[Lou]

I mentioned in another thread that you may go to the pool supply and buy pool shock that is 27,5% hydrogen peroxide, phosphoric acid stabilized, for about 15 USD. It is a gallon container, Baquacil is the name if I recall correctly.

Thanks for the lead, Lou.

I went out today and got a gallon of "Soft Swim" for $16.99- 27.5% material.

Way better than the 3% stuff, from a dilution point of view. I assume that you only add it as it is depleted.

I am also bubbling air through the container while the parts are being stripped, it seems to assist in agitation and reduces the amount of additional H2O2 augmentation.

Thanks again!

You can get h2o2 at the beauty supply at 20% to 30% and sometimes I've seen 40%, but usually only in quart quantities.

Has anyone worked with this company (SQM) for sodium nitrate?

In Canada a good supplier is www.prolabscientific.com they however will not ship to the USA, homeland security I would think.

The company that I am with, sells chemicals and labware.
We will ship many chemicals to the USA too.
We have full clearance from UPS.

I get all of the chemicals that I can't buy locally from Hi Valley Chemical in Utah. They can be found at www.hvchemical.com.

I recently purchased 70% nitric acid from a place called ACME Analytical Solutions in Hayward, California. Tremendously nice folks. I paid $24.15 each for four 1L bottles (and since I picked up on will-call there were no additional fees). From what I've been reading recently this is not as great a price as I originally thought it was, but considering I couldn't find it anywhere else (and don't want to mess with making my own presently) I was fine with it. But then now I see in their catalog I could've bought a 2.5L bottle for $38.75. D'oh! I'll chalk it up to experience. At any rate, I'll use the home-made HNO3 or the poor-man's AR recipe for general recovery and save this expensive stuff for final refining as it's lab grade.

Here is ACME's online catalog:

They carry a full line of lab chemicals.

I just found these people : http://www.gfschemicals.com and set up an account with them. They will not allow me to pick up chemicals from them but do have an "Express ship" option which will cost me $65 from their location near Columbus, OH to me in Marietta, OH. I need some advice, though, since they have many different grades of Nitric.

They list, among others:
Nitric Acid Solution, 1.0 N / $154.40 for 6 X 2.5L
Nitric Acid, Reagent grade, low lead / $159.50 for 4 X 2.5L
Nitric Acid, Superior Reagent ACS / $175.70 for 6 X 2.5L
Nitric Acid, Reagent ACS / $144.50 for 6 X 2.5L

They also offer optional packaging in PVC for a bit more.

Am I correct in assuming that the cheapest choice, Reagent ACS, is fine for simple recovery and refining of e-scrap? I want to buy enough to spread the shipping cost over a larger quantity and don't want to buy the wrong thing!

Would that choice be 70% Nitric?

If I plan to store it for a year or more should I opt for the PVC packaging? I'll store it in a dark cupboard.

Chumbawamba,

I'm curious. Why didn't you just buy 2, 2.5 liter jugs for a total of $77. Get a extra liter and pay $20 less.

gold4mike,

The reagent ACS will work fine. It should be 69-71% but ask to make sure. The 70% may also be listed as 1.41-1.42 specific gravity or 42 deg Baume' (Be'). All the same stuff.

I just hate to see both you guys paying so much. You don't need reagent grade. Sure you can't find a place that re-packages technical grade in 1 or 5 gallons.
