100 lbs of lead free solder

[DNIndustry]

Couldn't you control the growth rate of crystals by adjusting the amps? From what I've seen, the faster the crystal grows, the longer and less dense they are. Per9haps adding some sort of buffer to the electrolyte to make the crystals more dense.

What would be the best voltage and amperage to run said cell at. I actually have 320lbs now
Was going to cast to snores. Not sure what size would work best...input?

Thanks for the input. An update . there is 320 lbs now. I tested a smple with xrf. Some pd and some silver present
Not sure if the AUdit mode means it ignores gold?

There is a good patent on digesting tin/ lead solder with Fluoroboric acid and titanium metal shavings . depopulate boards.

Do you have a number or link to that patent?

How much acid do you need to digest 320 lbs? :lol:

Unless I am reading this wrong there is only .201% Ag in this lot. That's les than a pound of silver in all 320#. Sell it as Sn and move on.
