Leaching

Our new way to dissolve ores has made simpler the conventional process for rare earth ores and concentrates. 

When sulphuric acid is used to break down phosphate-based ores such as monazite, there are two main acids present:

We have simply removed the sulphuric acid, replacing it with additional strong phosphoric acid, in a simplification of the chemical system. 

The initial results of this work have been published after peer review. The process is patent pending under Aust. Pat. App. No. AU/2020/051252. 

The new leaching process is a cleaner and effective process.
