I have only a basic high school education but my insatiable curiosity has led me into this forum through some google searches I made while researching
for a project that I am working on. A desire to make money from scrap computers gave me the idea of using electrolysis to refine the metals. I have
found quite a bit of info on the internet on the subject but mostly it is so generalized that it leaves me with some questions that I can't find an
answer that I can understand. OK I have found some descriptions of processes that use electrolysis to refine pure metals. Some refineries use porous
ceramic filters in their process, which seems like a good idea to me. My question now is how porous? It must allow ions to pass through it but filter
out all the unwanted metals. So I started looking for information on ceramic filters and all I could find on the net was info on water filtering
systems. Would a store bought ceramic filter work for my project? How big is an ion. Are copper ions the same size as gold or lead ions?
I have also come across info that leads me to believe the voltage applied to an electrolytic cell affects the different metals differently
according to their electrolytic reactivity but I can't decipher the information due to my limited education. A simple chat that tells me what voltage
to apply to harvest copper etc. Is what I need. Hope you all can help me out with this. The end result of my project is to design a system that is
environmentally friendly, cheap to build and will actually be using electricity that can be obtained free. In fact I might even get paid for the power
that I use if my ideas all coalesce into a viable system.
Thanks that was one of the first sites I visited. I am looking at refining 99.999 pure metals without using acids etc in any large quantity. For a
hint on where I am going with this, take a look at the threads re: HHO fuel cells to power. Internal combustion engines.
