New dry process for cement clinker production. Copper tailings content is 16%. End-of-pipe treatment: Bag filter with 85% efficiency. When using this data set for life cycle assessment, special attention should be given to the cut-off criteria based on the ISO140 series of international standards, which focus on material input in relation to product quality. Inclusions and exclusions should adhere to the following specifics: (1) Ignore upstream production data for any ordinary raw material with input weight less than 1% of the total process material inputs or high-purity substances less than 0.1% of the total input weight, provided the total ignored materials do not exceed 5% of the total raw material input. For system environmental emissions data, contributions to LCA outcomes should be calculated prior to deciding on its exclusion. (2) Upstream production data for low-value waste materials used as raw materials, such as tailings, can be disregarded. Users need to ensure that the system boundary of the LCA includes the clinker calcination unit process and apply the data selection principles accordingly.
