It may well be on your dime, but an experiment needs to be carried out from a position whereby you can quantify results.
You can't, so it is all conjecture. What I find vexing is that you seem to have an aversion to straightforward answers, and that concerns me as inexperienced people will read your guesswork and think it has validity.
It could have validity but as I have mentioned already you have no hard data.
Your mistaken I have posted hard data with pictures and weights of the material recovered, if your after how much gold, silver or platinum group is present that information is not forthcoming.
My point. The yields are the hard data. Saying "i've got xx grammes of sludge" is not hard data. You're not doing this to recover sludge after all.
Rather than rip me a new one try using google once in awhile my experiment is based on research not conjecture.
I assure you that I'm not ripping you a new one. I'm asking you to be coherent and present facts not guesswork.
The circuit board itself, component leads and jumper wires all introduce copper into the solder in a wave soldering machine. ... Like the other coinage metals, gold and copper, silver will dissolve in the solder. Iron - Temperatures over 430°C will cause the solder to dissolve iron from the solder pot itself.
What's the relevance of this to the sludge?
