Gogold,
Now that I see your source material, I'm convienced your yields are beyond that which can be attained from the pictured scrap. The photo of the scrap makes me even more amazed at the reported yield. Here are a few reasons why I'm skeptical:
Judging from the information you've provided, I have to believe your gold must be contaminated with some base metals or silver. The photo of the button apears to be shiny and pure, but it does have some surface bumps near one side. Also it does not have the characteristic pipe that purer gold does. Lastly, the size of the four gram button appears large to me (of course no scale of reference was given, like a penny). Here's a photo of an 11.5 gram button I pulled from 5 lbs of fully fingered identical (all the same card source ) ISA fingers a few years back:
It's not super pure, but it does have the characteristic pipe I mentioned.
I'm not trying to discredit your work by any means. I'm just trying to figure out how you got such an extreme yield from mid grade (at best) fingers? Any other information you can provide would be great.
Steve
Now that I see your source material, I'm convienced your yields are beyond that which can be attained from the pictured scrap. The photo of the scrap makes me even more amazed at the reported yield. Here are a few reasons why I'm skeptical:
- You have several large surface area boards with minimal thin gold plating on them included in the batch (i.e.: whole memory sticks with surface mount components on them)
- The majority of the finger boards are low to medium grade scrap. (i.e.: Partially fingered newer ISA and PCI fingers)
- The batch is of several mixed types of scrap, the bulk of which is low to mid grade.
