Something i was wondering about.... I also caught no fume hood, i was wondering.... does that room have a secondary exhaust fan for emergency blow downs to vent the room or is the only exhaust through the scrubber system.

...was still soooo overwhelmed with my first attempts. First time I got a positive stannous test I wanted to cry lol. I do though have a fume hood and foundry furnace. I have been prepping for a few months. I do appreciate any and all advice. Ill definitely be watching this post for any...

I actually run stripped copper parts straight in a copper cel. Even gold and platina plated jewelry goes in without even melting. Foils and dust are collected in an anode bag. And black used dilute sulfuric from the stripping cell clears up real nice. Ready to reuse electrolyte. I love the...

...fume a bit to much and those fumes should be avoided. Keep the bottle safe so it don't fall down and break, maybe pour into another plastic bottle for daily/weekly use. And use it in a well ventilated area or fume hood. Be aware that the NOx fumes are as bad as the direct fumes from the bottle.

...from drawing moisture. Use that and the rooto sulfuric acid distill. The end product will be nitirc acid it will make more than 250ml. When distilling the idea heat is 317that is when you will produce the most concentrated nitric. Do this out side or in a vent hood. Fumes are extreamly hazardous.

...and also history of the stuff... To the plexiglass, use whatever you want. Plastic is generally quite resistant to the vapors inside of the hood. If nothing form mist or wet aerosols, it will survive for quite a long time. If there would be condensation, it goes rather quickly to the trash...

Please tell us how you do it, in detail. What you add and what you do with it before adding it and such. It is impossible to answer you with these vague descriptions.

First of all get some proper Glassware. Next study more, at least read Hokes book. You obviously have no hang of the chemistry yet. 2-3Ozt of Gold in there??? Siphon off the liquid, test the pH, then do a Stannous test. Continue based on that. The Solids can be redissolved and precipitated so...

...the values that are in the boards to do so To do this (800 pounds) yourself) you will NEED to ------------- 1) set up a "real" lab with fume hood & fume scrubber to deal with the TOXIC fumes 2) source all the different chemical you will be needing for all the "different" processes used in...

I’m using 1” diameter glass gems from a craft store

Belated happy birthday my hood friend and many more to come :cool:

You need a fume hood rated to handle acids, no metal parts. Gas mask will not protect you.

...to put a couple kilos in - for that unit to work you also have to work with corrosive & toxic chemicals - so you have to have a lab with fume hood/scrubber etc. to go along with that "unit" In other words - that "unit" is only "part" of what you need to refine 90% gold to 999 fine gold Kurt

Thanks for the input. I have been curious about this process and have even watched those videos in the past. I think you should be more careful with the cyanide side of these chemicals. Even a crude fume hood would be a big help in getting the fumes away from your face, and lungs.

...chemicals but very little on avoiding SMB fumes. If your working outside, work in a cross wind. Being upwind, if a breeze does come up, it will often cause a swirl effect and bring the odors back in your face. Even a cheap home built fume hood that simply raise's the fumes over your head will...

...annually for heavy metals. I have no allergic reactions around Pd, skin or respiratory. Key points to Pd safety: 1) work outdoors or in a fume hood. 2) don't allow Pd compounds or salts to dry out keep them wet or in sealed containers. 3) don't touch and/or eat around Pd salts/compounds...

...point. I am working from 4metals designs on putting together a scrubber. It will be overkill and work with a semi closed reactor in the fume hood which leads me to my question: I am thinking of constructing a small fume hood from a plexiglass aquarium. I got the idea from a post on page...

I’m using frp panels on luan so a chemical resistant silicone will work

Goldshark, there is no need to be rude or to use vulgarity here. Keep your responses civil. Dave

I come from the world of professional refiners and all, or most, use scrubbers and all use good exhaust hoods. It’s when I started posting here that I learned of those who often use neither, and even work upwind! So just making everyone aware of the potential hazards has become a habit. I...

Do you have a fume hood, PPE?

HIGHLY unlikely that it is Pd plating - the likely hood of that being Pd plating is next to zero - if not zero aniaxi is spot on here - Pd plating in this application (transformer cores) simply has NO reason &/or purpose &/or function for being there whereas permalloy actually has...

I appreciate the advice . This goes out to everybody that took the time to put give me their important information . I'm going to cease my refining till I read up on Hokes literature and get a safety plan, proper and complete tools/ equipment and allot more knowledge before I start back up...

...can melt it, and do a basic assay on it, (via XRF) now all we have to do is show you how to refine it! First off you will need a good exhaust hood. There are many threads here on the forum concerning hoods and building them, a DIY section in the library will get you started on that project...

...filters and small bits and setting up a safe outdoor work area. If that first attempt works out decently then I am thinking of building a fume hood and moving forward towards gold and unobtanium! My main interest is going forward with strength and learning what works the most efficiently and...

It will only TEMPORALLY filter out anything. Use it long enough and it will be useless. Is it really worth your health or life? NO! Get a proper ventilated fume hood in a separate building from where people live. What is wrong with people?

...couple of places and I'm a total science geek, but unfortunately never worked with these types of chemistry (PMG). I was planning to use pvc pipe for the scrubber. PP and PE for extraction gear. If I build a bigger hood/scrubber I'll likely use used 55 Gallon drums, they are cheap/free if...

It is always good to know what have been done in that used hood. You do not want to buy some one contamined with unimaginable variety of nasty chemicals. If it is from some well established lab working with harmless stuff, OK. If it was from some other PM refiner who you does not know...

Edwin, If your 2 to 3 gallons of waste is still putting out SO² any gold that was in it is settled on the bottom of your container and yes I have done the same thing as far as over using smb. If you can decant the AR waste solution all the way to the material that has settled on the bottom you...

Thanks 4 metals this is my plan to keep use of my garage. Thanks for all the feed back from everyone.
