Process Data set: Alumina production ; Alumina for metallurgy ; Bauxite (en) en zh

Key Data Set Information
Location HEN-CN
Reference year 2018
Name
Alumina production ; Alumina for metallurgy ; Bauxite
Use advice for data set When using this dataset for Life Cycle Assessment, consider the following: 1. This data represents a cradle-to-gate evaluation of alumina for metallurgy produced from bauxite without detailing individual process units. 2. If the alumina is further processed or recycled post-production, subsequent life cycle stages should be considered separately. 3. Users should ensure alignment with the technology and practices of the assessed period, indicated by the year of dissertation publication.
Technical purpose of product or process The alumina produced in this process is intended for use in metallurgical applications. It is typically utilized as a primary feedstock for the production of aluminum metal through the Hall-Héroult electrolytic process. The high-grade alumina ensures efficient aluminum smelting operations.
