1,000,000 plus SIM cards

Sounds fishy to me. The information on those cards can easily be destroyed. Shredding the cards pretty much ruined everything. How will you know all the gold is actually there? It's possible that some cards had the "chip" removed and then the non valuable part was shredded and thrown into the lot as filler. Never mind now that you have to deal with the ENTIRE card instead of just the gold part. Walk away!

I've been following along hoping for the best for you but...

They used a grinder on the cards which means they most likely hit the gold spots. If they even touch the plating, you have 0 gold as it is thin to begin with.

At this point, it is too much work unless free which still might be too much.

Bummer

All,

An update on fuel card, the guy whom I contacted regarding the cards communicated with me that due to security issues they can't hand me the cards unless it is shredded and grinded, which I requested to send me a sample to investigate and test, I assume for treating that massive amount of cards shredded and grinded best option would be a shaking table or jig, please advise.
He confirmed 800,000 pieces already processed like that (grinded) and 400,000 more this month.

What a bummer - I would have to agree with the others - its time to walk away - to much plastic which is "ALL" going to have to be incinerated = "HUGE" amount of ash = can't wash ash away without losing gold plating = excessive flux to slag ash off in the smelt + more collector metal to collect from ash = more chem work &/or electrolytic work + lost plastic sales ++++

was really hoping this was going to work out for you Kevin but I really would walk away at this point

I understand that I am new here and that this is an old post but why not just soak the cards in acetone? The Plastic just swells up and pushes the gold and chip right off...

Welcome to he forum. I think using hot lye solution is what has been used on smaller quantities of sim cards, but this post was about over a million pieces of simcards which is shredded and dumped into the landfilled.

by doing some rough math you will get a sense of the volume of 1,000,000 sim cards.

I have try that, and it is possible with the pvc based cards.I havent try with the other plastic type there is used at cards.
But it is a mess and it is nessesarey with two or three soaks in clean acetone to remove all the pvc.

Acetone cost a whole lot more than acid or naoh and it explosive on top of that.
