Title: PROTACTINIUM EXTRACTION

Abstract

A method of producing and separating protactinium from taorium containing solids is described. The protactinium is formed by irradiating thorium containing solids, such as thorium dioxide and thorium tetrafluoride with neutrons. The protactinium is separated from the thorium solids by contacting the solids with a non-squeous solution of hydrogen fluoride and a complexing agent, NO/sub 2/. The protactinium complex formed is soluble in the non-aqueous solution, whereas the thorium solids remain insoluble in the solution. (AEC)
