| Abstract: | As the output of rare earth Nd-Fe-B production increased,the pollution caused by producing tombarthite production became worse.Through an analysis of the production environmental impact of Nd-Fe-B permanent-magnets with LCA,the results showed that environmental impact load was 70.286mPE for 1 ton of Nd-Fe-B permanent-magnets.The environmental load was derived mainly from dust which was 62.354mPE and accounts for 88.7% of the total load. |
