Following the increasing demand in battery metals, the production of lithium carbonate or lithium hydroxide from hard rock is gaining importance over the traditional production from brines, with spodumene ore being the most frequent hard rock source.

Recovering lithium from spodumene concentrate requires an initial thermal treatment at above 1000°C to transform mineral into a leachable form. This calcination step, also referred to as decrepitation, can beneficially be executed in Circulating Fluidized Bed (CFB) furnaces, which present significant advantages over traditionally applied direct fired rotary kilns in terms of energy efficiency, heat recovery and maintainability.

Our expert, Mrs. Agnes von Garnier, will be sharing more information on how CFB calcination technology benefits lithium calcination in an upcoming webinar.

After this webinar, you will understand:

How CFB technology can be used for spodumene calcination, while significantly reducing the energy consumption compared to other technologies
When best to apply CFB technology for a specific spodumene concentrate
Which options for heat recovery can be implemented into the process flowsheet
How CFB spodumene calcination has been demonstrated at pilot scale for a multitude of concentrates
