ENUSA mines an ore‐body in the ‘Schisto‐greywacke complex’ near Ciudad Rodrigo, close to the Portuguesc border. The uranium ore (pitchblende) is associated with sulphide minerals (pyrite, chalcopyrite). The whole Spanish yellow cake production (250 t U∼Os/year) is obtained from this mine (MINA FE) by bioleaching, although at the beginning, in 1973. it was an acid heap‐leaching operation.
