Apr 19, 2016· I have been looking at and toying with this same question for an advanced hobyist's point of view. I would say forget about acids for depopulating and leave that for proffesional refiners. I have tried heat.

Oct 09, 2009· bien ese es el proceso que yo estoy utilizando; con excepcion de que luego de obtener las laminillas fundo, con plasticos incluidos, y obtengo un metal que contiene oro; luego lo hago granalla y lo disuelvo en agua regia, luego precipito, etc.
