Looking for input / current prices you guys are getting on the following wires found in computers
-Power supply : are these copper, ones I've stripped look like stranded aluminum, of course could be copper tinned.
-IDE cables: Current price?
-SATA: Copper? Are the connectors gold plated?
-Misc / speaker / signal: These also appear to be either stranded aluminum, or tinned copper.
Thanks!
There are posts on this, they are copper tin coated or silver coated but they are practly worthless. my yards buy them as "com wire" .40 per lb, unless you can find an economical way to strip them. if you do let the rest of us know.
About the only thing I want off a computer would be CAT5 cables, and power cables. Anything else, i.e. that angel hair wire is worthless to my machine.
Actually, there is a way. Pyrolsis.Quote:

Distilling and condensing some of the gases back to fuel (e.g. diesel or other longer C chains) and burning the rest of the gases.
What's left in the reactor is the metal wires + carbon black that can easly seperated by sifting.
4 products are obtained: Clean wire, Carbon black, liquid fuel and combustible gases.
I have experimented with this before, using a small pressure cooker and copper piping loaded with 1 pound of wires each time. The combustible gases fitted with a bubbler and burned under the reactor once the reaction had started... in a sense, this system is somewhat self supporting.
I have never scaled up this process, mainly due to lack of room and supply of wires, but my estimates were and remains that the reactor should hold around 150-200 lb of high gague wires, and electrically heated.
It takes some setup and there is a learning curve, but it can be an awesome thing to do and may be very lucrative assuming you find a use/buyer for the products.
i love this forum
just my thoughts.Quote:

I mixed my IDE cables, (with the gold connectors clipped off) in with what I consider low grade wire... stuff from USB cords, monitor cables, some phone cord, keyboard cords and some really thin wires from inside computers and other electronics. My yard has 3 grades for insulated high, medium and low yield, they graded it as medium yield 55% copper by weight and gave me $.81 a pound.
I'm specifically saving the rainbow colored wires from the power supplies seperate since I'm starting to get a lot of them. Was wondering what grade these wires tend to get at other yards. I know High Voltage said he doesn't even take the stuff, but from my experience the yield from them isn't that bad percentage wise.
I just bought about 300 lbs of them as a favor and the heck if they were not ALU!!! I was most ticked. :)
Oh and I don't take them because I don't export. I use all the wire that I buy domestically. There is value in them for scrappers. If you are going to sell to a yard or an exporter. I believe they are considered low grade though.
Just so there is no confusion, I'm talking about this type of wire, not the super thin ones that connect to the LEDs, little fans, etc.

Does anyone get consistantly better than low grade wire price for these?
Those go in the tote for our #1 insulated, our yard buys it that way;
M688...But aren't a lot of the power supply wires alum?
All the ones I broke down so far had silver colored wire but testing with a file shows it is actually copper wire that has been tinned or coated in silver.
What I see is tinned copper, making it look silver. There not actually using silver to plate that wiring.
Using the above process you can recycle tires. You will be left with the metal inside of the tire but will end up with alot of gas they can be used to heat you home and reactor along with diesel fuel. There was a guy down here who use to take all tires for free and he used them to heat his home during the winter...powered his truck and all ways had more fuel than he could burn. Ontop of all of that...he was paid by some of the bigger shopped to haul away the tires even tho he would of done it for free...but he would not tell them that lmao (take what you can). But he has now moved away from here and so I do not know if he is still doing this or not in another town. But I do know that doing this with used tires you will/can make a good amount of fuel and usable gas.Quote:

Iv'e seen a video on youtube where they use the gas to power a regular engine generator.
Sure can seve some money on electricity bills.
There are companies out there who sell biodiesel, maybe they would agree to buy the extra fuel generated if done on larger scale, as far as i know, tires should produce nearly pure diesel product.
The coke can be sold to iron/steel smelter.
Out of pure curiosity, would a process such as this is something,you, as a recycling company would consider to incorporate in your business?Quote:

So yes..we are doing something like this..but not the same deal.
What happend to the other posts in this thread?
Hmmm I had posts deleted here too?
