Key Data Set Information
Location CN
Reference year 2019
Name
Aluminum electrolysis ; liquid primary aluminum ; prebaked ; alumina for metallurgy
Use advice for data set Users of this data should note that the dataset is specific to the production of liquid primary aluminum with a focus on the electrolysis process using prebaked anodes. The energy consumption and emissions data included are specific to this process and may not be applicable to other aluminum production methods. When using this data, consideration should be given to the technology level and the specific environmental impact of the entire life cycle, including any subsequent processing and the end-of-life phase. Additionally, if modeling system boundaries, the user should carefully evaluate whether to include or exclude the impacts of alumina production, anode production, and any potential recycling processes.
Technical purpose of product or process This data set describes the production of liquid primary aluminum through the aluminum electrolysis process using prebaked anodes. The aluminum produced is typically used in metallurgical applications, where its properties such as lightweight, high conductivity, and resistance to corrosion are valuable for producing various aluminum-based products and components.
