Processing Black IC's - The wet way.

[glondor]

G.S.P. gave me a fairly strong warning about a year ago when I asked about wet ashing filters. I paid attention to it. Thanks Chris. Just a question before this thread goes away.

What would happen if sulfuric acid at working temperatures described in this thread came into contact with wood. Would the wood catch fire? Would you have a burning wood/ acid fire on your hands to deal with?

Can this process be done in a different manner such as it would be rendered safe? (safer) IE: over an extended period of time at room temps VS such high heat? Is high heat critical to wet ashing? Will room temp Sulfuric disintegrate the carbon over time.?

Sam. Just a note. Too bad the process is so dangerous. Your results are beautiful, A recovery dream. The good stuff is right there for your eyes to see. Would be a great method for determining yield per pound except for the carbonized fleshy bits if you screw up.

A proper protocol and process could be developed but the cost for a home refiner would be very high. Good job on the experiment. Once again your results are fantastic. I fear someone is going to try this and get hurt.

quick question...to increase the concetration of battery acid to make it suitable for cell use, one has to boil down the acid to 1/3 of its volume, right? so, how is the danger different from wet ashing?

Sorry to say, but if you have to ask this question this method is not for you.

Be safe and use incineration followed by crushing.

Has anyone tried the MEK mentioned towards the bottom of the dynasolve thread? If I can find it locally I'll definitely post up my results. So far no luck, just a bunch of substitutes that equate to being ethyl acetate, which will evaporate much slower I just have no clue if it will actually WORK(doubtful since most substitutes do less work for more $).

I tried some months ago MEK on PCB's trying to get rid of the solder mask, nothing happened. I have different black chips & IC's in MEK for the last 3 weeks, & they were not affected either.
I got my MEK from Home Depot.

I think I'll be incenarating.

i didn't want to come out and say it but,the reply i made above concerned the use of MEK.i would BOIL the black plastic chips in MEK.WARNING:unless it is your intention to make a massively explosive situation do not ever attempt what i just said.it is dangerous and fool hardy.i have alot of land away from everything and only endangered myself and tried to minimize that danger as best as i could.the plastic would become soft but never did dissolve which was my objective.i still wound up incinerating the material anyway.

The jenie is already out of the bottle :shock:
Deleting the post does not remove the infomation from those that have already seen it.

I feel that this needs a better explanation so those that do not understand can understand.

Some do not understand what hot concentrated sulfuric acid does to organic compounds. :shock:

I lack the ability to say it in a diplomatic way that most people can learn from without feeling scolded or worse, like wanting to try it just to see what I am talking about.
Can someone elaborate on what happens when things go wrong. Graghic details would also be good

I'm sorry Steve,
Tom C.

I would not try to stuff any genie in a bottle, but I also would not like to hear of a member or anyone else, just reading a couple of lines on the intranet (our forum). Mangled for the rest of their life.

When we have safer and proven methods to use instead of wet ashing.

We could write up all of the procedures and all of the safety concerns, and all of the pictures of when and why things go wrong, why you should not do them in your basement, when making explosives, but that would not help a mother who's son read some of the instructions, disregarded warnings and crippled himself for life.

That is just how I see this, no argument I see your point mine just differs.

I'm trying to post a pic of a person with an acid burn on his foot.

P.S. It worked.
Deleted the picture; added the link,

Sorry for the graphic depiction.

i too understand both sides.consider some of the processes we do on a regular basis,if done correctly there's still a fair amount of danger involved.why deny information such as this and promote others that have the potential to be as deadly.its an age old argument about censorship.its not the information that's dangerous but the person that doesn't heed the warnings of others more knowledgeable.instead of suppressing the knowledge, give detailed instructions on how to and the dangers of the process involved plus all the equipment needed.make it understandable to the novice that this is an advanced process, not to be attempted without first accomplishing all the processes listed in advance and only with approved equipment.give people a chance to decide for themselves if they can be responsible with the information provided.

No argument, Complete Agreement

What I was trying to get at is as long as this post stays up (not deleted) we should try to spell out the dangers so someone can't come back and say "why didn't you warn me that ..."

Personally, I would prefer for this post and the related post that talks about this process to go away or at least be hidden some way.

Just my opinion

I think those who know the answers are very reluctant to take on the responsability of instruction in this process due to the very real danger involved. The level of concern suggests to me that there is an order of magnitude jump in the possibility of serious injury above and beyond our regular processes. We should not consider some one not wanting to carry the burden for some ones misguided mistakes as censorship. All the instruction and care in a tutorial can not stop inattentive or undisciplined web surfers from making mistakes and hurting themselves or others. We have heard from professionals who would only use this method under very controlled conditions and with very small amounts. We should respect the ones who know and let this thread die. I think in the interest of safety for the members this thread should be
Deleted.

Here is a link to another graphic picture of a burn from Sulfuric Drain Cleaner.

The entire site is a great read, and shows how things can go wrong so easily.

Make sure to check this one out too. Fascinating stuff. I have spent hours reading all of them.

I agree with Sam and the others, delete it, both of them. Someone is gonna hurt themselves, its not worth it.

I tried to delete my posts from the other thread, but can’t. Please delete them.
Thanks

I must admit while this is a fascinating thread I feel the dangers outweigh the advantages.
I can think off only one acid more scary than hot concentrated sulphuric.
Perhaps delete the thread but post a locked thread about the dangers of wet ashing just incase it can be accessed from elsewhere, it seems to be alluded to on the net, with a warning in large red lettering pointing out why we don't advise it's use especially for the home refiner and the need for extreme caution by the professional.

 

[lazersteve]

I feel the gory photos should be linked to via hyperlink, not embedded in the text of the post.

Very graphic.

I think this is much like keeping a gun in your house and not having a long talk with your children. Don't think for one minute they won't find it and the ammo no matter how well you hide both.

Far better to have the talk than to wish you did.

 

[ericrm]

my opinion is to delete this post
what ever the way you think about it,it is a bad idea to keep it.
i will tell you why in my opinion we should delete this post
i f we take the fire arm as a comparison, in canada we have less fire arm than the us but also less accident,the reason is simple ,it is not the fact that you teach your children to use a gun that will make them hurt themself ,it is the fact that is an UNVOLONTARY ACTION that will lead to an accident.
if you didnt understand what i means ,you can teach as much you want about sulfuric acid,nobody will be stupid enuf to put his finger in... even if it happen only one time in a tousand when the beaker slip/crack/broke/boil(or whaever isnt suposed to happen) somebody will catch it by reflex... now say that we are 200 to know the process,risk are low for an accident, but with forum 5 000 000 poeple know the process 1in 1000 x 5 000 000
TO ME THE RISK OF UNVOLONTARY INCIDENT ARE HIGHER TEACHING SAFETY WITH THIS METHOD THAN JUST HIDDING IT
also if im not convincing enuf 8.99 for h2so4 and a mason jar over an hot plate,i will assure you that someone will try it,and the mason jar WILL broke.
anyway this is my opinion

Show of hands, how many members are here on the forum because you get the whole truth as opposed to the half baked B.S. you find anywhere else on the web?

Here you get what works and what doesn't, whats safe and what isn't.

Those that proceed once they have all the facts, you weren't going to save from themselves anyway.

Aren't those that concentrate their own battery acid for the cell doing the exact same thing?

Anyone want to try and push mercury back in the bottle, or do you openly discuss the safe use, or alternative methods?
