Alumina production ; Alumina for metallurgy ; Bauxite ; 2015
Use advice for data set Users of this data should take note that the LCA data includes information on the production of alumina (PA), supporting activities (SA), electricity, and other background data. The methodological considerations for utilizing this data should include the sources from which the PA and SA data are obtained, specifically statistical data and relevant literature. In addition, users should ensure that their LCA models align with the localized Chinese context by incorporating the background data from the CAS RCEES 2018 database, encompassing aspects such as energy, materials, transportation, and waste management within their analyses.
Technical purpose of product or process This data set refers to the production of alumina specifically intended for use in metallurgy. The alumina produced from this process is derived from bauxite and is used primarily in the aluminum smelting industry to produce metallic aluminum through the Hall-Héroult process.

Data selection and combination principles The data in this study refers to the LCA data of PA, SA, electricity, and other background data. The PA data were obtained from statistical data sources, and the SA data were mainly obtained from the literatures. The background data were mainly derived from the Chinese localization LCA database CAS RCEES 2018, which was established by the Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences and covers LCA data for energy, materials, transportation, waste management etc.
