All About Keyboard Mylars

Every mylar is not made the same, nor do they contain the same amount of silver in them. As a matter of fact, some mylars don't contain silver at all, but are carbon. And some mylars have silver and carbon covering them, which can make recovering the silver very hard, but not impossible.

* There is an average of 78 mylars to equal 1 lb.
* 1 lb of mylars will yield around 12 - 15 grams of silver
* 1 lb of mylars will yield a different amount of silver than another mylar.
* It takes approximately 2 lbs of mylar to yield around 1 ozT of silver.

There are many types of mylars out there, and I have come across mylars that contain silver but I have no idea of what component they came out of. I'm going to post pictures of them and if someone can tell where they come out of, I'm going to compile that information so that way if I can get at least 2 lbs of them I can give an accurate yield data on them.

Some of the mylars I am processing right now I feel that if I had at least 2 lbs of them, they would probably yield more than 1 ozT of silver.

I also had some rectangular sheets sent to me that are 100% silver on one side of them. No lines or anything else, just the whole thing coated with silver. I'm sure those will yield around 1ozT of silver from just 1 lb of them. I wish I had more to determine the yields.

When I process them for others it's hard to tell which types yields what amount due to not having at least 1 - 2 lbs of that type. So, when I process them, I combine them all together, but, if I have pounds of a particular type (standard keyboards, PBX phones, etc,.) I do process them separately so I can get the yields from them.

Are these the single sheets found inside some LCD computer monitors?

Actually, I don't know what they came out of. But if I had to guess, I'd say maybe a monitor of some type or an iPad. I'm going to take pictures of the exotic mylars I have so I can get more data on them.

I have some touchscreen POS units that have a mylar over the touch screen. Tracing is on the outside around the screen.

It sounds like I have some of those too. Can you upload a picture of the device and mylar?
