Because GRC said 181 lbs and I saw 167 lbs
I am going to use the returned material weight at 151+ lbs
15+ lbs of trimmed fingers
44 + lbs of printed circuit boards
32 + lbs of cpu 20 lbs high grade 12 lbs low grade
7 + lbs of misalliances
53 + lbs of pins and connectors
5 lbs of gold plate contact points
32 lbs of cpu (20 lbs high grade 12 lbs low grade) and 15 lbs of trimmed fingers leaves more then 100 lbs of material left, including 5 lbs of gold plated contact points, as well as the difference of total true weight I sent in.
Look at the guide and do the math….on the lowest yield.
Before I sent my material out, I did my own stripping of fingers using AP and refined it with vinegar and bleach and I got 1 ounce of gold with only 10 lbs fingers. This tells me that there is more then 2.7 ounces
When I use the Gold Mining Guide (at the lowest yield) I should have lot more than 2.7 ounces. And don’t count the Gold Mining Guide out. It was published to help the forum members. I watched more then 5 different videos on each of the cpus, fingers and pins striping and refining and they matched the yields of the guide. I would like to see the proof from the naysayers as to why the guide should not be used as a reference.
Remember that this was high grade e waste (high grade because of old industrial and commercial electronics as well as old cncs, telecommunications equipment, old industrial computers). and this is why I got the high yield.
For those that still say that 2.7 is fair - educate me. No one has yet.
I have given you my side of the story. Enough of me, and my experience, lets move on.
The forum was started to help fellow refiners and I came here to inform others about my experience with GRC.
Who else has had a experience of being cheated and how did you handle it?
