Target entity: Hall–Héroult process
Context triple: [Sohar Aluminium smelter, usesProcess, Hall–Héroult process]
  • A. Hall–Héroult process chosen
    The Hall–Héroult process is the primary industrial method for producing aluminum by electrolytically reducing alumina dissolved in molten cryolite.
  • B. Bayer process
    The Bayer process is the principal industrial method for refining bauxite ore into alumina (aluminum oxide), a key intermediate in aluminum production.
  • C. Birkeland–Eyde process
    The Birkeland–Eyde process is an early industrial method for fixing atmospheric nitrogen using electric arcs to produce nitric acid, pivotal in the development of large-scale fertilizer production.
  • D. Bessemer process
    The Bessemer process was a revolutionary 19th-century method for mass-producing steel by blowing air through molten pig iron to remove impurities, dramatically lowering costs and enabling large-scale industrialization.
  • E. Ostwald process
    The Ostwald process is an industrial chemical method for producing nitric acid by catalytically oxidizing ammonia, fundamental to large-scale fertilizer and explosives manufacture.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
