Abstract

A new technology has been considered to process monazite concentrate by treating it by a phosphoric acid solution in the presence of strong acid cation exchange resin. The end products are a carbonate of hydroxide concentrate of rare-earth elements (REEs), orthophosphoric acid, and thorium concentrate.

独居石精矿加工技术

摘要

一种新技术被认为是通过在强酸性阳离子交换树脂存在下用磷酸溶液处理独居石精矿来处理独居石精矿。最终产品是稀土元素 (REE) 的氢氧化物浓缩物、正磷酸和钍浓缩物的碳酸盐。
