The recovery and purification of plutonium involves interesting chemistry. Currently in use are several high temperature processes based on redox reactions. These processes include direct oxide reduction which uses calcium to reduce the oxide to the free metal and electrorefining which is used as a final purification step. The chemical research group at Rocky Flats is currently investigating the use of an aluminum/magnesium alloy to remove the ionic plutonium from the salts used in the above named processes. The results of this study along with an overview of pyrochemical plutonium processing chemistry will be presented.
