, Baotou 014010, China) Abstract: After rare earth separation by complexation extraction from Baotou mixed rare earth concentrate, the obtained waste liquid contains a large number of aluminum ions. The aluminum ions in waste liquid can be transformed into cryolite through a special processing technology, but the content of silicon in cryolite exceeds the content required in Chinese national......
