Scope

This standard specifies the determination of manganese in manganese ore by
potentiometric method and ammonium iron (II) sulphate titrimetric method.
This standard is applicable to the determination of manganese content in
manganese ore and manganese concentrates with vanadium content (mass
fraction) not more than 0.05%, the determination range (mass fraction) is as
follows. manganese content of potentiometric titration ≥ 15.00%; manganese
content of ammonium iron (II) sulphate titrimetric method is 8.00% ~ 60.00%.
