摘要
介绍了包头混合型稀土精矿、四川氟碳铈矿和南方离子吸附型稀土矿这3类主要稀土工业资源的特点及研究开发的一系列先进稀土冶炼提取工艺技术,并就目前工业上应用的冶炼分离工艺及研究进展进行了综合评述,探讨了我国稀土湿法冶金领域的发展趋势,提出下一步的研究开发方向和重点研究领域为:稀土矿高效绿色冶炼分离工艺,研究解决三废污染问题,降低单耗和提高资源综合利用率;超高纯及特殊物性的稀土化合物材料制备技术开发,拓展稀土应用领域。
Characteristics and hydrometallurgy processes for Baotou mixed-type rare earth concentrate, bastnasite, and ionic adsorption deposit in China were reviewed. The R ＆ D circumstance and new progresses in extraction and separation of RE elements in China were introduced. Moreover, the development trend of RE hydrometallurgy was predicted. The direction and emphasised fields of research and development are also brought forward as： to R ＆ D high efficient green progresses in hydrometallurgy and separation of RE ore, resolve the waste pollution problem of water, slagand gas, reduce the chemical material consumption and improve comprehensive efficiency R ＆ D preparation technology for RE ultra high-purity and special physical tending application fields of RE. of resources; to compounds with property for extending application fields of RE
