Abstract
NICKEL AND COBALT ARE STRATEGIC METALS THAT PLAY A VITAL ROLE IN UNITED STATES INDUSTRY AND DEFENSE. CURRENT PRODUCTION COMES LARGELY FROM A DWINDLING SUPPLY OF NON-DOMESTIC SULFIDE ORE DEPOSITS. OXIDE ORES SUCH AS LATERITES AND, IN THE FUTURE, MANGANESE OCEAN NODULES ARE MORE PLENTIFUL AND WILL BECOME INCREASINGLY IMPORTANT RESOURCES. EXTRACTIVE AND SEPARATION TECHNOLOGIES THUS FAR DEVELOPED FOR THESE OXIDE ORES ARE EXPENSIVE AND HIGHLY ENERGY INTENSIVE. WE PROPOSE HEREIN A NOVEL SCHEME FOR THE REDUCTION AND SIMULTANEOUS SEPARATION AND EXTRACTION OF NICKEL AND COBALT FROM LATERITES AND MANGANESE NODULES. THEPROCESS USES THE CARBONYL FERRATE ANION AS A REGENERABLE INTERMEDIATE WITH CARBON DIOXIDE AS THE ULTIMATE REDUCTANT. NICKEL CARBONYL IS EVOLVED FROM THE REDUCTION REACTOR AND COBALT CARBONYL SPECIES ARE SOLUBILIZED FOR LATER RECOVERY. THE SOLUTION RECOVERY STAGE IS CURRENTLY UNDER INVESTIGATIONIN A SEPARATE STUDY. WE PROPOSE HERE TO INVESTIGATE THE OREREDUCTION AND REAGENT REGENERATION REACTIONS SO THAT WE MAY PREPARE AN INTEGRATED FLOWSHEET FOR A LOW COST, LOW ENERGY PROCESS FOR THE REDUCTION, SEPARATION AND RECOVERY OF NICKELAND COBALT FROM OXIDE ORES. PRELIMINARY ENERGY BALANCES ANDCAPITAL AND OPERATING COSTS WILL BE DERIVED.
