Key Data Set Information
Location CN
Reference year 2019
Name
Alumina production ; Alumina for metallurgy ; Bauxite
Use advice for data set When utilizing this dataset for Life Cycle Assessment (LCA) of aluminum products, users should consider the origin and transportation of bauxite as well as the energy sources used in alumina production. Recycling processes for aluminum should be considered, as they significantly affect the overall environmental impact. It is important to note that transportation assumptions made in this dataset may differ from real-world scenarios and should be updated or verified against current local conditions. Energy intensities for end-use processes should be based on the latest available data to reflect ongoing technological advances and efficiency gains.
Technical purpose of product or process The alumina produced in this process is intended for use in the metallurgical industry. It is commonly employed in the extraction and refinement of aluminum from bauxite ore. This type of alumina is specifically processed for use as a raw material in the production of aluminum metal through smelting and casting processes.

Data selection and combination principles Inventories of energy input and material flow are collected from updated yearbook s, published papers, official reports and databases. The details of the inventory are presented as Table 1. It should be noted that the data for the material transportation assumptions are based on relevant studies, whic h may be slightly different from the actual situation. The life-cycle intensities of each end-use energy type are based on the results of our previous studies.
