At the store stannum sells at 50 bucks for 1kg. But I don't need that much, I need only 20 grams (to make a stannum solution to check for gold). And I have a lot of motherboards. How do I extract pure stannum from a motherboard with acids?
TIA

There are threads there that deal with this. The actual method of refining is not discussed on this forum. I believe there is a rule regarding this and it is meant for the safety of all.
