This paper studies the technology and theory of preparing of ion sieve from ocean polymetallic nodule and lithium hydroxide, and recovering of lithium by the ion sieve from complex lithium-low solution system
First, the studying achievement is summarized about ocean polymetallic nodule, such as formative mechanism, ore phase and application situation. At the same time, it is introduced such as development situation of lithium resource, technology of recovering lithium from Brine Lake and other unsolved-...
