Thanks for the links.

SWIM has read many posts about this disposal. No real consensus on what to do.   Using the nitro Al/Hg What to do with the gray sludge after extraction. 

Would adding more Al be enough to neutralize the Hg and then flush or bottle to the landfill?

A lot of post keep talking about Copper or Zinc fillings.

Steel machine shop turnings are readily available  :)

Must remember SWIM is a little slow. Must have details.

So take this sludge, throw in ??grams of steel turnings, mix well, then what?  Throw in a jar and landfill or flush?

Then SWISS needs to speed up. :)  Many useful details can be found in the thread starting with

Post 103272 (missing)

(ymir: "Mercury Recovery/Disposal", Chemistry Discourse), which is linked to in the post above. There's no need to keep reposting the same information for the sake of those unwilling or unable to search and read  :)

SWIM has studied and searched fairly well. Don't think real good answer is out there. SWIM sees about 5 different options. Has no idea which ones are right.

OPTIONS:
1. All the Hg is already converted by the Nitro Al/Hg. Place sludge in milk jug and throw away.

2. Seperate the Al particles and place in jug, flush the liquid

3. Place more Al in the sludge, let stand for 5 - 8 hours, seperate, solid in jug, liquid gets a flush.

4. Mix suflur Powder in the sludge and flush.

5. Mix Iron/Steel turnings in the sludge and bottle and toss.

A lot of methods keep talking about recovery of the Hg but don't think that is goind to happen here.

Also confused that if Al will react all Hg then seems way to easy to just add more Al to make sure and throw away. But if that were true why are there so many posts on these other methods.

SWIM is trying and know that other newbees must be having the same questions.

Still don't know what option above is best and whether to flush or jug it and toss?

Pardon my friend officer, He's a little slow.

Disposing of mercury wastes into the water shed is not only bad for the environment, but totally unnecessary. Your basified sludge contains elemental mercury, which will amalgamate to metals such as iron, zinc or copper. You take a 20 L/5 gal bucket with a tight fitting lid, throw some clean metal turnings in the bottom, and then your pH 13-14 sludge. Attach the lid firmly. Over a period of time, the mercury is amalgamated, siphon the sludge for disposal down the drain. Keep the lid on the bucket for future use. If you're determined to dispose of the mercury instead of recycling it using nitric acid, you will need to solidify the turnings within plastic, thus isolating the mercury from the watershed. This would be most easily done by slowly portionwise (so as to avoid melting the bucket) pouring molten plastic into the bucket until the metal turnings are completely encapsulated  :)

Thanks for the post lugh.  Now that SWIM reads what you posted the other posts make a little more sense. 

Said earlier that SWIM was not interested in recovery of the mecury using Nitric Acid. Now changed mind.  Searched all up and down TFSE and didn't find anything clear enough for someone like SWIM.  If SWIM were to try and recover the Mercury (Hg) from the post Amalgam sludge where would a good step by step bee?  See lots about distilling mercury, SWIM has no idea what distilling elemental mercury would be, sounds like a damn mess.

Pardon my friend officer, He's a little slow.

You probably won't want to bother with recovery until you've got more than a couple of grams amalgamated. You will want to keep the lid on tight to prevent the escape of mercury vapor. While SWIL has never done the recovery, obviously because of the volume of turnings compared to the amount of mercury, one would want to use very dilute nitric acid, and then evaporate the solution to obtain the mercuric nitrate.

whenever you decide to change carrears.  take all the mercury encapsulated in the plastic and deliver it to a DEA facility.  They will spend a few thousand dollars and much time trying to figure out what it is.  those fuckers spend so  much money tryin to figure out shit,  make more work for em.  Mix some other fun shit in it too so they need suits to discect it.

Since swim has not drempt this yet.  will the HgI be dissolved already in the alcohol. if so could the bottle just be poured into the al/MeOH mix. Question here is soloubility of the HgI in the IPA that the tincture comes with.

The Hg2I2 dissolves itself in the alcohol present in the tincture.  Then, you can just pour the tincture into the aluminum/methanol mix, and stir on high for one minute to thoroughly mix.  That's how ISO has been doing it, very even and fast amalgamation that way.  ISO rinses the tincture bottle with MeOH, to be sure to get all of the Hg, and to make the bottle safe to throw away.  Has anybee out there tried this yet?  Please post results to this thread, so this method can be validated.  Otherwise, ISO will be forced to nudge this thread back to the top every week with a little B.S. post until someone else trys this too :)
Trust me, the reaction proceeds exactly the same as with HgCl2, you will not be disappointed.

No need to hurry/worry, it is known and said numerous times, especially by Osmium, that any Hg salt will do a fine amalgamation job on f.e. Alu foil or thicker alu sheets.
So, we TRUST you on this one! LT/ ;)

Hate to keep posting but believe that V_L has the right idea about the tinture. Just add 5g Hg to one bottle. Then pour about all liquid and leave what should be 4.5g Hg blob in the bottle.  Add more tinture, repeat, parsley, serves two.

This to me make sense to SWIM for a couple reasons. 1. Don't have to fuck around measuring how much Hg was put in the bottle, (vapors, scales, and shit).  2. Basically should only have to touch mercury once per 10 bottles.

Pardon my friend officer, He's a little slow.

Superstar:  It might be harder than you think to pour off the tincture without dumping the blob as well.  It's easy just to zero a plastic container on a balance, and have another container with the mercury.  Just tip the container poke the Hg with a glass stir rod until you pull a .3-.5g blob into the container on the balance.  Dump it in the tincture, replace the lid and shake the fuck out of it to break up the blob, which increases the surface area of the Hg. ISO doesn't think mercury vapor is TOO much of a risk, mercury having a high B.P., and probably creates very little
vapor at room temp. and atmospheric pressure, but ISO doesn't know that for a fact, so someone flame the fuck out of me if I'm wrong.

Seperations can be done in a measuring cup careful decantation is an art.

I don't  agree with you LaBTop. You said that any Hg salt works just fine, but when I asked about HgSO4, some bees said it won't work. So use HgCl2, since it's cheap and easy to get.

Life without chemistry would be a mistake.

Mercury spills can be easily neutralised with Chemizorb® Hg absorbant. This kit is supplied by Merck and can be used to neutralise the contaminated area up to 1 m2. But probably you won't be able to get it, so here is an OTC version of such an absorbant:

Cleaning up Mercury spills:
First collect the drops with a pipet, put them in a bottle and seal it. Those droplets that can't be collected are covered with a paste, that consists of copper powder and diluted H2SO4. Instead of this paste you can use a suspension of Ca(OH)2 and powdered sulfur in hot water. The paste (suspension) is removed after 24 hours and disposed off properly.

Life without chemistry would be a mistake.

Amounts too small for a pipet can also be recycled by using transparent cellulose acetate tape to pick it up, and then acetone to remove the mercury from the tape  :)

After you clean the spill with the chemizorb.  Used the amalgamated chemizorb to reduce a nitrostyrene.

> This mix was added to a larger volume of methanol, and the experimenter noticed a very small portion of greenish-yellow solids remained undissolved in the bottom of the flask.

Please clarify for me here:  Does Hg (or I2 for that matter) dissolve in MeOH?  Swim has some I2 crystals he would like to react with some elemental Hg to form HgI2.  Is MeOH a good medium to perform the reaction in?
