摘要
将磁处理技术应用于碳酸氢铵沉淀稀土母液过程中,研究结果表明,采用合适的磁处理条件能提高稀土的纯度3%～4%,并得到晶型碳酸稀土。为淋积型稀土矿山的工艺改进,矿山的综合效益提高开辟了一条较好的途径。
Application of magnetic treatment in precipitation process of rare earth lixivium by NH_4HCO_3 was researched in this paper. The results show that under proper conditions the magnetic treatment can increase rare earth purity of 3%～4%,and obtain crystalline rare earth carbonate. A good approach was found for technological improvement of strain amass-type rare earth mines,and a satisfactory route was provided for increasing overall social and economic benefit of rare earth mines.
