would it be possible to dissolve the Noxx fumes in distilled water

What a awful thing to say. Why in the world would we want to dissolve noxx in distilled water? He's a pretty cool guy, what did he ever do to you.

I'll take that one on the chin Viacin :lol:

PB, good point, I was forgeting about the other fumes involved in AR,
maybe it would be possible when dissolving base metals in Nitric.

lol marty, I couldn't resist. I was speaking of the humble creator of this forum, Noxx. http://goldrefiningforum.com/phpBB3/memberlist.php?mode=viewprofile&u=2

I just couldn't resist

 

[Noxx]

Ahhahh Why would one wants to dissolve me ? :shock:

Getting back on topic,

If I remember correctly, Hydrogen and NO fumes are not soluble in water in a significant amount.

Thanks for your response Noxx, if what I proposed isn't possible then thats something I've learnt today. It was just a thought that maybe we could control the BFRG and reclaim and reuse some chemicals rather than dispose of them. At least by using lye the Noxx fumes are controlled and neutralized

 

[Noxx]

By the way, It is NOx fumes not Noxx...

The x represent a number. Like there are NO2 fumes and NO (nitrogen oxide) fumes.

Sorry for the insult Noxx! Sometimes my fi9ngers just type random keys.

NO2 forms nitric acid when combined with water. NO is soluble in Nitric acid. Nitric acid is used in commercial scrubbers to collect NO. Nitric acid is also present in the marble collector.

I put qst's idea to the test today. I must say it worked wonderfully! My BFRC stoped immediately and the nitric began dripping back down in a matter of minutes. It is simple, easy to set up, and works great. I recommend it to anyone running nitric or AR. It also kept the neighbours from calling the EPA/911, so big A+'s there as well.

Be careful though, your gold can bubble up inside the bottle if you have a vigrous reaction. So don't forget to wash it out over your filter! Also, have another beaker or something handy to place it in while stirring or boiling your solution, as it will tip over.

I give it 5 stars out of 5 and plan to use it for a long time. Maybe once I get set up in a permanent shop I will get a bit more technical, but this is all one needs to control their BFRC effectivly.

As requested here is a diagram and and instruction of the absorption train.

Enjoy!

qst42know, now that is what I like to see creative thinking
That is so simple its better then great. add a fune hood to that and it dont seem like theirs much left to worry about.

What, if anything is in flask # 2?

Thanks. I hope to hear how it works for you.

Though it appears to be a rediscovery of an old technique. After I began using this condenser I have seen one old lab glass cylinder full of marbles on eBay, and another 1 pound lot of tiny marbles from a well known lab supplies company.

Anyhow it is within reach of anyone wishing to keep fumes under control. I no longer worry when my dogs need to come out where I'm working.

Pawnbroker Bob stated on page three of this thread #2 is empty.

 

[wop1969]

Pawnbroker Bob
very clean, simple and effective.

I think I will try both, put a cylinder between flask 1 and 2 that is full of mables and you got the best of both techniqunes
put flask 4 under a fume hood and life is good (if nothing goes wronge)

If you are using HCL/CL any condenser will work to reduce fumes.

But if you are using AR approximately half of the nitric acid is driven off as gases. The effervescence (fizz) can carry away PM values.

If you can keep the marbles above the vessel so that they drip back into your reaction you retain most of the nitric usually lost as a gas and return the PMs to your reaction vessel.

Before I started using the marble condenser It was common for me to find purple speckles of colloidal gold on the outside of the pot, on the top of the hotplate, and on the work surface. Granted the amounts are small but can add up over time. If you have a filtered fume hood you can collect these values in the filter and process them periodically, but I feel it is more efficient to collect them at the source.

Half the nitric, that is allot, no wonder the gas is so bad
I aggre, collect at the source.
I will run the marble setup on mine at the least

Could you make a combination of the two where the marble scrubber could be combined with the four beakers lye/water solution to neutralize all of the NOx that escapes from the marble scrubber?

 

[Noxx]

Yes why not ?
