Lepidolite to Lithium Conversion., page-13

You are missing the point, such technology is proven in the lab, it is only a matter of time for production plants to start being built. Have you had a look at the lit content of Spodumene to Lepidolite or Micaseous Pegmatites, a good Spodumene has 1-2% Lepidolite has 2-5%

You need to understand that most breakthroughs came out of a lab or they would not exist.
The process of obtaining lithium from Spodumene came out of a lab, and now it exists, Lithium from Lepidolite exists. Time to wake up to disruptive technologies flowing through the lithium markets.
