Hi Kev,

I guess you could but you would need hundreds of them to make it anywhere near worthwhile.

The plating on them is very very thin.

Sim cards strip nicely in AP. Some have multiple layers of gold.

R&B,

About how much gold would be in 1000 sim cards?

 

[Rag and Bone]

I'm not sure. The most I ever did was 300. Much of the gold got dissolved and went into another AP batch so I didn't get yield data. The surface area of gold on the sim cards varies widely.

I would love to have a pile of them. They strip really clean.

The reason I asked is 1000 just sold on ebay for $69 including shipping. I didn't think they were worth that much so didn't bid.

Recycle.net has them priced at $16-32/pound. I don't know what they base their prices on, some of them seem really bizarre.

As with most good e-scrap, your'e probably looking at a few grams per pound tops. 1000 sims is probably only a few ounces. Lot's of speculation here, don't base your decisions on my fuzzy math.

Ive processes 10 or so '3G' ones and they seemed to be nicely plated as they completely stripped off in nice foils in AP. It wasn't enough for me to do a yield or anythign and the foils just went into a pile with others.
In the middle of the gold plating, one of the foils looks kinda like a golden cat converter haha

Also, Ive been gettign toner contacts from printers from my work lately. Not a lot but each one has 2 half square inch gold contacts and they also strip nicely in AP.
