RE:RE:RE:RE:BALLOONS + HYDROGEN
100% agree about Wango. He's got some great ideas floating out there. Like I said, processing refractory ore will be a future reality....the research is bring done as that increases the world's reserves by at least 25% High grade easy deposits are fading, and lower grade complex ores will become the norm as seen in copper/lead/zinc/aluminum. As far as roaters go I think there are a few items that lead to the expense: 1. Materials used to handle the combination of heat and corrosive conditions are expensive. 2.Getting the infrastructure in place to deal with the SO2. Essentially you are building 2 different operations. 3. Environmental considerations....although with today's technology you are able to scrub and collect over 99% of SO2 from the process.
