Summary[edit]

Description
English: This picture was taken while I was recovering some gold from broken electronic divices. Lots of gold is wasted every year all over the world and the few times it is recovered it is done by people who does not work in safety conditions, so as long as you can afford a decent safety system you can have fun and see how is chemistry such a nice thing.
