摘要
综述了从硅铍钇矿中提取工业氧化铍及混合稀土的工艺,介绍了硅铍钇矿经硫酸浸出后,利用稀土复盐和草酸沉淀稀土,使铍和稀土得到有效分离的机理。生产中已分别获得了混合氢氧化稀土和工业氧化铍。
After H 2SO 4 leaching of ytterbite and RE precipitation with RE compound salt and oxalic acid, Be can be effectively separated from RE. By this way, RE mixed hydroxide and commercial Be oxide can be obtained.
