    Hi all, I was looking through YouTube during the week and this bloke in NZ had a video on refining ic chips without incinerating he had a ball mill made out of a 9kg gas cylinder, he shows you how he built it and what he done to make it work better, similar to what Geo done with the cement mixer but he used a 60mm ball bearing to do the job and also he had it going for at least a couple of days but he did crush them down to fine powder
    He also goes through all the procedures including recovering the gold and refining it's a long one at movie lengths of around 90 minutes but he explains it pretty well

    If your interested that is

      Yep, if you go a few posts back we speak about him and I put up a couple video's of the milling, and his refining video a few weeks ago in another thread
