Gold isn't difficult, as opposed to silver, which seems to look identical to lead. tin, solder, etc.
In what places are you most likely to find silver?

there is silver in the solder, in key board mylar. in some ribbon cable and mylar on hard drives and other components, also on some mylar in printers.
don't know for a fact but have read the recovery of silver in e waste is much greater then the gold.
"anyone who thinks scrappin is easy money ain't doin it right!"
There is also silver in all refrigeration solder joints. Most silver solder runs from 15 to 45% silver content. Just need to find someone to recover it for you.

That's cool, because I see all that silver(color) in there and can't help but wonder, am I tossing lead solder or silver here?
Maybe that's what I found tonight in an old Sun server I just pulled apart. One of the SCSI cables is clear with silver looking wires and much stiffer and heaver than other SCSI wiresOriginally Posted by olddude

does silver melt as easily as aluminum? I tried a lighter to some silver IDE cable wires last night, and they melted right away, so I figured those were aluminum

olddude pretty much hit the nail on the head.You just don't hear much about the silver because when people hear the word gold they get gold fever and its all they care about.
Silver melts at 1571 F
Alu. melts at 1220 F

Also tin melts around 450 F

what temp does a lighter burn at ?
Metal Recycling Entrepreneur
bic lighter - 1,977 degrees Celsius or 3590.6 degrees Fahrenheit

At that temp it would melt them all pretty quick
Hey Bear, I have started collecting breakers to get the silver contacts. They are pretty easy to ID if you bust open a breaker they will be soldered on to the copper arms (actually sometimes steel also). I also go for motor starters and pump pressure switches. The bigger breakers/starters like 400 amp and more have several good sized silver contacts on them. I don't have a value on them yet. I do plan on doing a breaker breakdown soon.
I wish I had someone near me who was a refiner because all the refrigeration solder joints and radiator solder joints I see at the yards just go into #2 copper.
Oh, and the obvious. I just got three pounds of silver solder sticks. They tell the silver content right on the tube.

I think I recall that silver,tin, and lead are some of the most difacult to separate.
the silver in flat cable and mylar will be thin and flat. the larger round wire in flat cable is usually tin coated copper,
most servers have a white plastic/mylar runner usually attached to the bottom under the mother board, I believe these all contain silver flat runners.
I would fruther venture that the solder in chinese products contain more lead and less silver because of the lax eco standards there and the carless attitude toward their work force,

the ram that is silver colored is that really silver?
Metal Recycling Entrepreneur
Nope. Tin, just tin.

haha! When they were selling it to us it was ; )

Some batteries contain silver, relays and my favorite 2nd hand stores/ auctions. As mentioned earlier concerning the breakers, seems that items requiring the most current have the larger and/or more abundent contacts. So an item with a 120 cord would contain less than a 220 v item. At this point only a visual observation no real data yet.

I make my own silver testing solution that will test, according to the color, the purity of silver and other metals such as:
.925 .800 .500 silver
German silver
Nickel
Copper
Brass
Lead
Zinc
Aluminum
Platinum
Would anyone be interested in the testing solution and a color guide if I were to put something like that together for forum members? I would only charge the cost of the actual solution, and shipping. I would be willing to do this at cost if there is enough interest.
I think of it in this way. If I can help forum members determine the type of scrap they are breaking down, they will be able to make more informed purchases which would benefit any refiner they were selling to and in the end everyone does far better.
I can't do this tomorrow, or even before Christmas, but if there is enough interest I can do it in the first part of January.

Silver contacts is my preferred refining job. I've done 100's of TOz of silver contacts.
First lets define different type of contacts.
High amp relays and motor starts with no waffle back after refining have run 82% (+-3%)
High amp waffle backed contracts are tungsten oxide with silver after refining they run 40%- 60% depending on composition.
small silver contacts small relays, range switches, old dryer switches. Thees are Cd Ag and they run about 60%-80% Ag as well.
small relays and switches that have Ag over Cu are referred as silver copper clad like today's American money.
Other types of contacts are out there as well like Pd contacts for phone switches they have a different shape like a trapezoid.
****Waffle back contacts********** look like a waffle patteren and they break/shatter not bend
Silver solder can be refined but HVAC people are hard pressed to waist any. One friend says that it is so expensive that he saves all of his scraps to remelt into bigger bars. Taking Silver solder out of HVAC joints is a waist of time.
Any other question let me know. Just don't melt your contacts they may and do contain Cd which will kill you. This is the reason the refiners don't take contacts the disposal is to high.

how about vehicles from the 60's and older, probably find a fair amount of silver coins in them =)
I buy and sell all types of scrap and escrap. I buy specialty and hard to sell escrap. I buy resale items. PM me or contact me at jghilino@hotmail.com
I AM ACTIVELY BUYING ESCRAP OF ALL TYPES. BOARDS, RAM, CPUS AND MUCH MORE
