SELECTIVE RECOVERY OF NICKEL, COBALT AND MANGANESE FROM SEA NODULES WITH SULFUROUS ACID

摘要

SELECTIVE RECOVERY OF NICKEL, COBALT AND MANGANESE FROM SEA NODULES WITH SULFUROUS ACID Nickel, cobalt and manganese are recovered from deep sea nodules by leaching with sulfurous acid. In addition, selective extraction of nickel and cobalt from copper is achieved by suitable adjustment of process variables such as leaching time and volume and concentration of acid.
