how is lithium extracted from spodumene by bioleaching

Efficient extraction of lithium from β-spodumene by direct ...

Abstract This research describes the study of a new process for the extraction of Li from β-spodumene by direct roasting with NaF and leaching. Various parameters including roasting temperature, β-spodumene/NaF molar ratio and reaction time were studied. The thermal behavior of the mixture β-spodumene/NaF was studied by simultaneous thermogravimetry and differential thermal analysis.

Spodumene has a theoretical Li2O content of 8.03%. Due to its high lithium content, spodumene is considered the most important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates
