一、工艺简述四川冕宁攀西稀土矿是80年代末我国发现的第二大稀土资源,它是一种单一的氟碳铈矿,具有易采、易选、易冶炼的特点。它除稀土外,还含0.02~0.03%的钍,6~8%的氟元素等。如何综合利用好这一宝贵资源中的有价元素,建立资源节约型,产品经济型,环境友好型的冶炼工艺是关系 First, the process briefly Mianning Panxi rare earth mine is the second largest rare earth resources found in China in the late 1980s, it is a single bastnaesite, with easy to adopt, easy to choose, easy to smelt features. In addition to rare earth, it also contains 0.02 to 0.03% thorium, 6 to 8% of fluorine and so on. How to comprehensively utilize the valuable elements in this valuable resource and establish a resource-saving, product-economical and environment-friendly smelting process is the relationship
