摘要
采用硫酸-复盐法从钕铁硼（NdFeB）磁体的废料中制取氧化钕（Nb2O3）产品。实验结果表明，该工艺技术稳定可行，所得Nd2O3的纯度大于95％，产品收率大于85％，其他工艺技术经济指标均较理想，具有推广应用价值。
Nd2O3 is obtained from NdFeB scraps by H2SO4-double salt process.Laborato ry-scale test shows the process is stable and practicable (purity of obtained Nd2O3＞95%,re covery＞85%,other techno-economic data are quite satisfactory), and worthy to be popular ized.
