Abstract

Acid leaching of ocean polymetallic nodules was investigated, CO and N₂ mixture was used as reducing gas and fluid medium. The effects of operation parameters on metal leaching rate such as reducing temperature, time and atmosphere were analyzed. The results show that under the condition of reducing temperature of 700-850°C, reducing time of 10 min and CO volume ratio of 20%, an average leaching rate higher than 95% can be achieved, which indicates the ocean polymetallic nodules can be reduced efficiently in fluidized bed.
