我国氟碳铈矿资源丰富,是世界上最大的生产国、消费国和出口国。随着稀土的广泛应用,深入研究稀土的冶炼工艺及研发高效提取工艺也越来越重要。目前我国主要采用湿法冶炼工艺,冶炼和提取单一稀土金属过程中一直伴随着氟的污染,本文重点介绍几种湿法冶炼工艺中的氟的存在形式及污染情况,通过分析选择经济与环境最优化的冶炼方法。 China is rich in bastnaesite and is the largest producer, consumer and exporter in the world. With the extensive application of rare earths, it is more and more important to deeply study the smelting process of rare earths and to develop an efficient extraction process. At present, the wet-smelting process is mainly used in our country, and fluorine is always accompanied with smelting and extracting of rare earth metals. This article mainly introduces the existing forms and pollution of fluorine in several wet-process smelting processes. By analyzing the most economical and environment- Optimized smelting method.
