The primary aluminum ingot casting process described here is utilized for the production of virgin aluminum ingots from liquid primary aluminum. These ingots are typically used in a variety of applications including automotive, construction, electrical, and packaging industries. They form the raw material for further processing into aluminum products such as sheets, extrusions, cables, and foils. When utilizing the data related to the primary aluminum ingot casting process, attention should be paid to the methodological consistency with the inventory data sources. Users need to consider the statistical nature of the data provided by the Nonferrous Metals Industry Yearbook, in addition to the specific technological data from typical enterprise production processes and technical indicators. Pollution emissions data from specific production stages should include internal enterprise statistical data and relevant research findings from referenced literature to ensure accurate impact assessment in LCA studies.
