Do any of the DD companies have patents over their recovery processes? I have followed these threads for about two years and have never seen any references to patents. A small Australian company called Geo2 Ltd, geo2.com.au has done a lot of research in the field of ion exchange resin beads as applied to precious metals recovery and registered patents (pending). This research has been carried out at several universities and with the assistance of the CSIRO. In fact one of the principal research scientists from the CSIRO joined Geo2 after a R&D Syndication was set up to fund the commercialization of the process. Geo2 now has a non-cyanide trial plant which is being sent to China for one year trials. The processing will start at 10 t/p/d and build up to 100 t/p/d, it is small and very portable. They also own a refinery. However the ore being used is high grade oxidized material, this should generate a quick positive cash flow and allow further development of the technology. Where does this leave companies that do not hold patents over their processes?
