Is the gold refining forum a part of this group? I would like to get started in refining metals myself. I buy old lab equipment and computers and have just been saving the circuit boards and other weird stuff. I think I have all the equipment needed to refine metal sitting in the warehouse. Have been using the Paul O Abbe ball mill to make sea glass instead of crushing the ic chips. So far the only refining I do is melt irony aluminum into ingots (watch out for magnesium air drills). I have been scrapping forklifts, electric motors, motor starters, welders, and transformers for several years now and just started removing the contacts from the backing again. I do this under a vented lab fume hood.
