Roasting
Sodium Oxide Roasting. It is to produce sodium salt soluble in water by roasting after adding an appropriate amount of sodium agents (such as Na 2 CO 3, NaCl, Na 2 SO 4, etc.) to the ores or concentrate. For example, in the process of wet extraction of vanadium, the vanadium slag is finely ground, and then the iron beads are removed by …

Direct Extraction of Lithium from α-Spodumene by Salt Roasting…
In recent years, several methods have been reported to extract lithium (Li) from spodumene. However, the majority of them still require the transformation of the naturally occurring spodumene phase (α) to the more reactive crystalline phase (β) by calcination at 1100 °C. To address the economic drawbacks and high greenhouse gas …
