How many of those strips does it take to make 1 gram of gold?

jmdlcar said:resabed01,
If you are going to refine those in the picture you need to clean them better then that. How many of those do you have? Do you have another type of strips? If you want to sell any send me a PM.
Thanks

That's why I want to do the yields to know for sure. Right now I have 550 ACCU-CHEK strips and 510 TRUEtest strips. Plus 3 kinds of silver strips which is a total of 625 strips. I'm going to wait tell April before I do any strips.kkmonte said:I don't think that .009 grams of gold per each is accurate, at least not on the ones I have. I refined 60 test strips, similar to the ones Resabed showed a picture of, I only had 60 test strips (used by myself), so I figured according to those calcs I should get about half a gram of gold. Well I pulled all 60 apart to expose the gold, I dissolved them with HCL and bleach, stirred it up real good, and it barely made my solution yellow. There was a slight tinge of yellow (A stannous test after 5 minutes showed no change, I then looked at the q-tip the following day and it was all black, it just took overnight to show). I then let it sit to let the chlorine dissipate , and the next day I dropped the gold with SMB. (or at least tried to). In a 200ML beaker, I see nothing on the bottom of the beaker, so there is that little bit of gold that I can't even see anything. I'm probably going to just add it to my stock pot for maybe processing the little bit that's in there later.
