A better method is needed to achieve the recovery of noble metals from          catalyst supports.  The failure of routine methods to accomplish this           separation suggest a major basic research effort to improve the key             operation for the desired process.  Research proposed to use a                  fluidized system to accomplish metal dissolution could be the key step          to supplement the developmental chemistry needed to arrive at a                 workable system.  The fact that a fluidized bed is more conductive to           continuous processing than the packed tower systems used in the past            offers strong promise.  Solids preparation, reagent concentrations and          fluid bed conditions must all be evaluated to determine reaction                kinetics for this novel system.  The experimental data which will be            gained from the research will be useful relative to the fixed bed data          for the same system and also for future extension to other fluidized            systems.  The use of fluid beds is relatively new in metals winning and         could awaken a wave of exploratory research for several of the high             value metals.
