Abstract: Nickel (Ni) is an important raw material for the production of lithium-ion battery material. Nickel slag is a kind of
industrial waste produced by wet leaching to produce NiSO₄. Increasing the nickel leaching rate in nickel ore can not only
increase the yield of NiSO₄, but also greatly reduce the production of nickel-containing waste slag and reduce the pollution to the
environment. By means of modern test methods such as ICP, XRF, SEM and EDS, the physical and chemical properties of nickel
raw material and its derivatives were characterized, the elemental composition and component proportion of nickel raw material
and its derivatives were analyzed accurately, and the nickel-containing intermediate products and waste residues produced in the
manufacturing process of lithium-ion battery material were analyzed qualitatively and discriminately. The analysis of the results of
ICP, XRF, SEM and EDS provided an accurate reference for the nickel improvement of the leaching rate of nickel-containing raw
material and the treatment of nickel-containing waste residue.
