Key Data Set Information
Location CN
Reference year 2019
Name
Alumina production ; Alumina for metallurgy ; Sintering method ; Bauxite
Use advice for data set This dataset should be used to model the environmental impacts of producing alumina for the primary aluminum production process. Users should ensure the exclusion of the impacts of bauxite mining from this data set as it focuses solely on the sintering process. The dataset might require updates with new technology changes in sintering processes or alterations in regulatory standards. The date of publication should be considered to guarantee methodological consistency and data relevance.
Technical purpose of product or process This dataset describes the production of metallurgical grade alumina through the sintering method using bauxite as the raw material. The produced alumina is predominantly intended for use in the production of primary aluminum in smelting operations as a critical feedstock component.
