Alumina production ; Alumina for metallurgy ; Bayer process ; Bauxite
Use advice for data set When utilizing this Life Cycle Assessment (LCA) data for the production of alumina by the Bayer process, attention should be paid to the methodology and scope defined in the study. Users must ensure consistency with the original system boundaries, including considering potential recycling stages and energy inputs relevant to the production of alumina. It is critical to reference and align with the standards and yearbooks mentioned in the data collection for accurate representation of the process. Modifications to the data should be done cautiously, and any assumptions must be clearly documented.
Technical purpose of product or process The alumina produced via the Bayer process is intended for use in the metallurgical industry. It is primarily used for the smelting and refinement of aluminum metal from bauxite ore. As a key raw material, metallurgical grade alumina is crucial for the production of a wide range of aluminum-based products in various industries including transportation, construction, and packaging.
