• Electrolytic Copper (Cu)
    Electrolytic copper
    Registered as ‘Grade A,’ the highest grade of the London Metal Exchange (LME).

    Electrolytic copper is high-purity copper with over 99.99% purity, produced by electrolysis of refining blister copper made using the flash smelting process and the Mitsubishi continuous process. The quality of LS MnM’s electrolytic copper has been recognized internationally, having obtained Grade A, the highest grade on the London Metal Exchange (LME), on top of being registered on the Shanghai Futures Exchange. Electrolytic copper can be applied to a wide variety of fields, thanks to its excellent electrical conductivity, thermal conductivity, processability, and corrosion resistance.

  • Crude nickel sulfate (Crude NiSO4)
    Crude nickel sulfate (Crude NiSO4)

    The electrolyte used in the electrolysis process of refined blister copper is concentrated and then filtered to produce crude nickel sulfate. Crude nickel sulfate contains more than 80% of Ni, making it ideal for use as a base for lithium-ion battery cathode materials, catalytic converters, plating and coloring of precursors.
