No comment from me, just some pictures, all referring to the preparation of 1 kg of the various indicated materials:





Table 1. Life Cycle Impacts of 1 kg REO Common to Bayan Obo Mines and Ion-Adsorption Clays

Table 3. Life Cycle Impacts of 1 kg NdFeB Magnets Produced by Two Facilities Using Two REE Sources





Have a nice evening.
