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.
