Downstream Processing

Downstream Processing

IGO’s strategy is focused on metals critical to clean energy, including nickel and cobalt, which are used in the manufacture of high energy density lithium-ion batteries.

Nickel sulphate is critically important in certain electric vehicle battery cathodes, particularly for battery technologies using nickel-cobalt-manganese (NCM) and nickel-cobalt-aluminium (NCA). NCM and NCA technologies are becoming increasingly popular given their high energy density which, in electric vehicle applications, results in longer driving range. There is an increasing trend towards higher nickel volumes in these battery types, driven by the improved energy density properties that can be achieved.

IGO has developed a new patented process (the IGO Process) that can produce a high-quality nickel sulphate from nickel sulphide concentrate. This would unlock significant additional value for IGO by delivering; a) significantly higher payabilities than traditionally received from raw nickel-cobalt sulphide concentrate offtake agreements; b) a premium price for nickel in nickel sulphate compared to the London Metal Exchange (LME) price for nickel metal; and c) directly linking IGO to the energy storage supply chain.

Testwork and studies using the IGO Process support:

  • Extremely high metal recoveries
  • Low costs for the integrated production of nickel sulphate
  • A more environmentally sustainable process compared to the traditional production methods for nickel sulphate, due to significantly lower emissions, power consumption and waste generation
  • Ability to produce high-quality nickel sulphate for use in batteries

IGO released an update to the market on 2 April 2019 on its Downstream Processing Study. View the full ASX Announcement here: https://www.igo.com.au/site/PDF/2701_2/DownstreamNickelSulphateStudyUpdate
