Do's and don'ts of scrapping crt monitors and tvs

When I used to scrap with a guy years ago he would just bust out the screens and the yard would take them as whatever they consider the bulk metal when you just empty out your truck. Not sure if all yards do this. But reading now on what I should do, is there something illegal about breaking the screens? Also, how worried do I have to be about getting shocked? I have always heard you have to be careful with this. I'd like to just give it a go and just learn as I go, taking it apart but any other things I should watch out for or separate? I have been keeping circuit boards from everything I can and any other non ferrous metals I can salvage. If I take out the copper and such would I still be able to bulk junk the remnants as weight? Hope that part isn't confusing!

Your asking if it's ok to smash leaded glass on tube tv's?

I'll refrain from my first reaction an say something nice.

You need to a search on here. You'll find our views on smashing glass.

Hello? Wall? Are you available? I need to beat my head against something.

Sirscrapalot - Seriously?

if you break the screen you will be shocked!

As for one that does many crt's (over 2000this year) I never break the glass . There is plenty of info on here about doing it safely and properly. But before you even start ask yourself ," what do I do with the glass and plastic ". I have somewhere to take them for free. Some states charge a fee. I also charge to remove them unless it's whit other scrap.

Questions like these rile up those of us who do the tv's right.

It's been said before on here, an time for it to be repeated I think..

If you can't do it right, and/or dispose of it properly...DON"t DO IT.

Sorry OP not trying to be a ****, but this is/used to be a commonly asked question, as said above..those of us that do it, do it right, or we don't do it. Hence why a lot of folks on here won't mess with tube tv's or monitors.

Sirscrapalot - OMG Becky! Look at her butt...it's so...BIG! - The annoying chicks at the start of Baby Got Back.

Yeah, that's a big no-no.

Yes, lead can be recovered from leaded glass. Its pretty much an industrial process, involving separating the leaded glass on the picture tube from the unleaded glass, crushing the glass and extracting the metals by chemical means. Some processes are done at high temperatures with the molten glass. Some of the chemicals used are not so user friendly, like Nitric acid, although there are several processes and the chemicals used can be more or less toxic.

Here;s a summary from a 2013 patent on one method of removing metals from glass:

Lead and/or Indium cam be recovered from cullet containing indium and/or lead, such as cullet from CRTs and flat panel displays. A chloride salt melt including AlCl3 is used to dissolve the cullet. The melt may be electrolyzed and the lead and/or indium and other metals may be selectively electro-deposited from the salt melt. The two steps may be combined in a continuous process.The salts in the salt melt are not consumed but can be recycled, with exception of the flux due to formation of chlorine gas and alumina. It is also possible to recover lead and/or indium and other metals from the salt melt by vaporizing the respective chlorides and condensing them, or by leaching the salt phase in water and extracting the metals as hydroxides by hydrometallurgy methods.

Not stuff that is done easily in one's garage! Sounds like at step or two more complicated than recovering gold from electronic waste.

Yeah you guys are pretty much reiterating what I've read. And I'm sure the guy I scrapped w was an idiot. HE just needed some help and I needed money. I'm surprised the yard took them without asking or noticing just the screens were broke out. It's a big yard too. I just hadn't come across the why or how to dispose properly of the glass. Just that ppl dispose of it differently. So are you guys dismantling down to wires and bolts or merely removing the screens and scrapping them whole as a certain labeled scrap type. I've been reading and watching a lot for weeks but literally everything is new to me and I gotta clear some space to get more. I'm interested to find out what causes the shock or what else is released when doing so. Anything else besides the glass I should be researching?

I thought it was ignorance is bliss lol you just have to remember, it may seem common knowledge to you or any other experienced scrapper but I've never encountered the subject or needed it til now. A lot of people do this in my line of study and expect people to know things that seem everyday to them and easily research able but if you don't know what your researching, questions become necessary on our forums as well. Not to mention not everything you find is right. So asking someone currently experienced helps confirm what your reading.

Also don't forget what happens when u make assumptions. I never had a reason to think anything was illegal. I was just stating observations with no basis for judgement of either. I guess I get the answer I did for assuming people who roam scrap forums that are supposed to be there for people to ask questions about, to them, the unknown would have an interest in teaching their specialty. Not ridiculing for asking.
