摘要
以离子型稀土矿四分组的ＴｂＤｙ 富集物为原料，用萃取法分离提取９９．９８％ 的高纯Ｄｙ２Ｏ３ 的工业试验已获成功，总回收率达９８％ ．采用本方法提取高纯氧化镝，成本低，回收率高，产品质量稳定，明显优于离子交换法和萃取色层法．
The industrial\|scale test on production of high\|purity dysprosium oxide (99\^98%) by extraction has got success, in which the enriched TbDy from the four\|grouped ion type RE mineral was taken as raw material and the overall recovery reached 98%. This method is characterized by low cost, high recovery, stable quality and is obviously superior to ion\|exchange and extraction\|chromatography. The product quality has reached the best level in our country.
