Pictoral Tour of Various Electronic Scrap Types (Part 1)

[jmharris]

Hey everyone. I'm pretty new to this forum/ website and think everyone's info is extremly helpful. I have recently just ordered my HCl, Nitric Acid, and SMB for trying to recover gold plated items. I have recieved Hoke's book from this website aswell, and have read about 200 pages and then re read the same 200 pages. I think im ready to give this a little try. I have posted flyers in stores, and even put an ad in the local paper for anyone wanting to get rid of there old computers.

I do have a few questions, if thats alright?

1. Would you expect anything out of this printer, which I will post the pic?

2. What is the best computers to try and refine gold plating from?
ex. household cpu towers, or should i go bigger , say try and find larger telecom style things?

Thanks everyone for any info that you have for me,

Jeremiah

I know that some of the old RCA tuners had a lot of gold on them. Pull one apart. If it's one of the ones I'm thinking of, it's obvious.

Poking around an old abandon barnyard property, I came across an old portable (black & white ?) TV that had been smashed just laying their with it's innards exposed.
So I grabbed the circuit board and when breaking down the tuner I found this little phenolic resin board.
I have no idea what make or model TV, but it was the old style tuner before remote controls. You had to get off the couch and turn that big knob, thump thump thump.
Not much here, you would need a truckload of tuners to make a BB, a semi truckload.

PS: Thanks Chumbawamba for a great post

TELEVISONS newer lcd types. dont waste time on the whole tv. cut only the lcd montior boards out they contain 98% of the gold on any LCD tv. the monitor board is ususally on the top of the tv take a few screws out bust it open rip board out. saves abut a hours work.

 

[GoldmanM]

Something from me.

 

[GoldmanM]

And more.

 

[GoldmanM]

And so on.

:roll:

 

[GoldmanM]

For now this, i will upload more.
Thanks for watching.

 

[kdaddy]

Goldman, would you tell us where the items came from? I think thats what the OP was trying to do, otherwise the pic's are useless and just clutter the thread.

 

[GOLDbuyerCA]

I disagree kdaddy ,,, [/GoldmanMb] is showing some pics, of scrap type. The items came from Your Big City surplus, end of line product, obsolete items, that contain gold. GoldManMb,
has them in hand, rather clear photos, some lesser, some more. it does take effort to sort them all, " buy sell , selvage " but the switches, are more valuable to Hobby builders, "yes,
there are a few left " Now a simple test, which pile would you rather have ? pic. :> in this example, original equal value parts, with plate, those with tin, , Audio builders, like the Au plated
parts. the difference, about 90 cents, the parts go for tops a buck each, the shiny ones. Thanks GoldmanMb, for your pics, , i think this thread, can hold some more good photos, PS,
i am having fun, now, more time to play, , this is part time, spare time for me, i have read the posts here for several years, just getting a little more active with the pics. Cheers all.

Pictures are great when they serve a purpose. But keep in mind that they require storage space on the servers and consume bandwidth every time a member checks the thread, leading to higher costs to maintain this forum.

Disagree all you want, you can go to Google images and see random pic's of escrap till your eyes bleed. Everyone else is describing the items or where they came from until you and the other guy started posting random pics without descriptions. You could post 200Gigs of photos of scrap without describing anything but how would that help anyone? I'm just saying, if you are too lazy to describe the photos or say where the items came from, you are not doing anyone any favors.

These come from 3Com 4400 series switches. I'd like to find the cable that attaches to them but haven't yet.

I'm thinking most pics aren't stored on GRF servers or else {img}{/img} wouldn't require a link to the pics location elsewhere on the web, such as photobucket, where I keep all my pics.

 

[FrugalRefiner]

kane,

I believe you're right. When you link to pictures stored elsewhere using the {img}{/img} tags, it doesn't require server space for GRF. But with the exception of the images you just linked to, all of the other pictures in this thread are attachments, not links. I believe those images reside on the GRF server space.

Each method has its pros and cons. Linking to images stored elsewhere saves GRF server space, but if the image host disappears, or if the account is closed in the future, the images disappear from the forum. You'll see plenty of examples of that throughout the forum. Images posted as attachments require GRF server space, but they are permanent unless deleted by the original poster or a Moderator or Noxx.

Like I said, pictures are great when they serve a purpose.

[DarkspARCS]

Satelite WGT board (Found inside LNB gun as well as wall mounted connection terminals)



Glass Digital Displays (Found in Recievers, Stereos, Boom Boxes, etc.)



Whats so special about these? Platinum! Platinum components as well as embedded platinum circuitry, found on its back side

 

[macfixer01]

This is a nice effort but ultimately will be a waste of time implemented as photo attachments. There are so many old/(not really that old) posts here already where the pictures are just gone for no reason I can imagine? If someone had the time and resources, the pictures in this thread should really be collected periodically into a pdf file.

 

[kdaddy]

Darksparks,

I'm curious about your claim that LCD displays have platinum circuitry and components.
I have never heard that before and would like to know more about it.
Could you please provide some more info.

Thank You

 

[Grelko]

Another "bump" of an old thread, but there is good information in here.

If I would have known about the glass displays having platinum in them about a month ago (if this is accurate?). Except I never seem to find this information until after I take things to the scrapyard. Atleast I know now.


So far, it looks like all of the flat screen TVs out there "old/new", seem to have the mylar ribbons in them. Normally they will look something like these. The green and gold/copper colored ones are usually attached between a circuitboard and the screen itself. (based off a random assortment of atleast 75+, LCD, LED, Plasma, DLP, Projection screens, plus some computer monitors.



Alot of the time, they look gold plated just at the very ends, sometimes copper, silver "or tin?", and the rest of the ribbon seems to be copper or aluminum. The white ribbon is usually silver colored, but I've found some gold ends. The white ones are also found in many other items like printers, scanners, cd players, DVD/VCRs etc. Also, on the back of some of the green ones where the numbers are, it looks like a small silicon "glass" chip, but I'm not sure if it would contain any PMs though.

Edit - Where the small silicon chip is on the green ones, between the glue and the chip there are MANY tiny wires connected to it, all the way around, that look to be gold plated. Probably atleast 100+, like bonding wires for an IC chip. Really small, maybe 1/6mm. Don't just peel the chip out though, you should cut around it, or you can miss alot of the tiny wires. Also, sometimes the green ones have 2 chips.



I'm trying to figure out what the best way to process these ribbons would be? "without nitric"

Clip off the ends, then straight into AP like ram fingers, or HCL/CL, or even just melt them into a bead (like keyboard mylars)?

 

[alchamplin]

First I would like to say what a great resource this board is! It's great that you all share so much. Regarding the Mylar Strip with gold plating (which I have a lot of from credit card processing machines etc.) do you process the gold with chemicals like gold plated metal? Or is there a buyer for the mylar strips as they are?

Thanks,
Alan
