Key Data Set Information
Location CN
Reference year 2019
Name
Alumina production ; Alumina for metallurgy ; Combined process ; Bauxite
Use advice for data set Users of this data should consider the specific technological context of alumina production for metallurgical purposes. Attention should be paid to the integrated sintering-layering process when utilizing this data for life cycle assessments or other environmental impact studies. Ensure that the data is applied only to scenarios relevant to primary aluminum production and that any emissions data or energy use is consistent with the sintering-layering combination process.
Technical purpose of product or process Alumina for metallurgy, produced through the combined process from bauxite, is primarily used for the extraction of primary aluminum. The substance is processed in a single operation within the aluminum production units utilizing a sintering-layering combination technique.
