Study of mixed hydroxide deposits (MHP) from local minerals
resources in Indonesia
Mixed hydroxide precipitate (MHP) is an intermediate product of this
process. MHP is an intermediate product of nickel which is used as
the main raw material in the production of nickel sulfate, which is important for
lithium-ion battery supply chain, specifically the batteries used
nickel-rich cathodes such as nickel-manganese-cobalt (NMC).
