Use advice for data set Users of this LCA data should follow the market-value based allocation method to estimate the environmental impacts of REO production unless there is a specific reason to use an alternative allocation scheme. It is important to apply this data with the understanding that it represents a conservative benchmark of the environmental profile of REEs. Additionally, when extending or applying the data to evaluate the production of individual REE or REE-based technologies and products, ensure that geographical relevance is considered, i.e., Chinese-specific data is used for China, and European LCI data is used when applicable to other regions.
Technical purpose of product or process Rare earth oxides (REOs) produced through this process are utilized in various applications including electronics, renewable energy technologies, and manufacturing of advanced materials. Specifically, they are integral in the production of powerful magnets used in wind turbines and electric vehicles, as well as in catalysts, glass additives, and metallurgy.

Functional Unit The scope of the LCA is cradle-to-gate and the functional unit was chosen as 1 kg of REO.
Technological representativeness
Technology description including background system The process chain for REO production includes mining followed by beneficiation, calcination, extraction, and roasting stages, see Figure 2. The first step in REO production is mining, wherein crude ore is blasted and transported for further refining. Crude ore abstracted from the Bayan Obo mine is composed of both monazite and bastnasite.
