摘要：

The separation was studied in the presence of magnesium nitrate and compared with the separation in its absence. As a useful criterion served the expression A/Z (part of Er in precipitate divided by the degree of decomposition). Under all conditions the separation was significantly better in the presence of magnesium nitrate. The method was used to concentrate the heavy yttrium earths (YE) Er, Tm, Yb and Lu from 38 kg to 10 kg YE2O3.
