稀土胶体形成和聚沉的研究

Study on Formation and Coaglulation of Rare Earths Colloid

讨论稀土胶体形成的各种条件和影响因素。结果表明，碳酸氢铵沉淀法提取稀土过程与稀土胶体的形成和聚沉密切相关。

The conditions and the effects on formation of rare-earths colloid are studied. The results indicate that rare-earths are extracted by the ammonium hydrogencarben precipitation method depending on formation and coaglulation of rare-earths colloid.
