[PDF] Processing hard rock lithium
The general process for recovering lithium has been to begin with a roast to improve the dissolution rate of lithium ions. This occurs by expanding the crystal structure from an alpha to beta-spodumene form. However, this initial roast contributes a significant energy expense in processing the ore.

Lithium Production Processes
Table 3.1 lists major lithium-containing ores, their chemical formula, and lithium grade. The processing of these ores initially involves comminution of raw materials, followed by beneficiation using techniques such as flotation, magnetic separation, optical sorting, or heavy media separation to produce concentrates containing 4–6% Li 2 O. 7., 8., 9., 10.

Mining for Lithium: Lithium is often recovered from brine, or water with a high concentration of lithium carbonate. Subsurface brines trapped in the Earth's crust are major source material for lithium carbonate. These sources are less expensive to mine than from rock such as spodumene, petalite, and other lithium-bearing minerals.
