COPPER CONCENTRATE PRESSURE LEACHING - PLANT SCALE-UP FROM CONTINUOUS LABORATORY TESTING

摘要

Phelps Dodge Mining Company (Phelps Dodge) is operating apressure leach vessel (PLV) for copper concentrates at the BagdadMine facility in Arizona. This single PLV unit was engineered andconstructed based on continuous laboratory testing, reaction chemistryand kinetics, and available pressure vessel technology. Thechallenge of designing for optimum process retention time, agitation,oxygen mass transfer, temperature and pressure will be reviewed inthis paper. The PLV interior lining, agitation equipment and compartmentconfiguration chosen for the PLV will also be reviewed.
