Novel extraction route of lithium from α-spodumene by …
In 1959, Peterson et al. 35 patented the possible extraction of lithium from α-spodumene using an alkali metal halide or their mixture (specifically, KCl and/or NaCl) in the presence of a refractory material. The amount of refractory material required by this approach was indicated to vary between 60 to 80 wt% of the quantity of spodumene treated.

are spodumene (Li 2 O, Al 2 O 3. 4SiO 2) and petalite (Li 2 O, Al 2 O 3. 8SiO 2). 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 ...

Natural spodumene is α-phase spodumene (α-LiAlSi 2 O 6), an aluminosilicate composed of a tetrahedron [SiO 4] and an octahedron [AlO 6].Owing to the compact structure of α-spodumene, its chemical properties are stable, and it hardly interacts with acids or bases, which makes the direct extraction of lithium almost unfeasible [13], [14].Thus, the traditional …

The process of extracting lithium from spodumene begins with mining. Spodumene ore is extracted from open pit or underground mines. Then, the ore undergoes crushing and grinding to release the spodumene crystals. Froth flotation follows, separating spodumene from other minerals. In the final stage, the spodumene is roasted at high …
