氧化铝排放（烧结-铺层组合工艺） ; 原生铝生产 Users of this data should consider the specific technological context of alumina production for metallurgical purposes. Attention should be paid to the integrated sintering-layering process when utilizing this data for life cycle assessments or other environmental impact studies. Ensure that the data is applied only to scenarios relevant to primary aluminum production and that any emissions data or energy use is consistent with the sintering-layering combination process.
