Acheson process for making carborundum

Target entity: Acheson process for making carborundum
Context triple: [Edward Goodrich Acheson, hasNotableWork, Acheson process for making carborundum]

• A. Shanks process for nitrate refining
  The Shanks process for nitrate refining is an industrial method developed in the 19th century to extract and purify sodium nitrate from natural nitrate ores, notably those found in the Chilean nitrate fields.
• 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. Rochow process
  The Rochow process is an industrial chemical method for directly synthesizing organosilicon compounds, especially methylchlorosilanes used in silicone production, by reacting methyl chloride with silicon in the presence of a copper catalyst.
• D. 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.
• E. 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Acheson process for making carborundum
Target entity description: The Acheson process for making carborundum is an industrial method that produces silicon carbide by heating a mixture of silica sand and carbon in an electric furnace.
