Key Data Set Information
Location CN
Reference year 2008
Name
Alumina production ; Alumina for metallurgy ; Bauxite
Use advice for data set When utilizing this data set, reference the statistical data from the Nonferrous Metals Industry Yearbook for information on various stages of primary aluminum production. For non-statistical process data, refer to surveys of typical enterprise production processes and technical indicators. Consider the inclusion of specific pollution emission data obtained from enterprise internal statistics and relevant literature studies to ensure accurate environmental impact assessments during specific production stages.
Technical purpose of product or process Alumina produced in this process is intended for use in the metallurgical industry, specifically for the production of primary aluminum. Alumina from this unit process is refined from bauxite and is used as a key raw material in aluminum smelting operations.

Data selection and combination principles In this paper, the production of primary aluminum at all stages is based on the statistical data in the non-ferrous metal industry yearbook as the main reference basis. For some non-statistical process data, they come from the research of production process and technical indexes of typical enterprises ...... Pollution emission in specific production stages is based on the internal statistical data of enterprises obtained from the research and part of the research results from the literature are referred to.
