    Lithium can be extracted from spodumene concentrates after roasting and acid roasting operations. A concentrate with at least 6% Li2O (approximately 75% spodumene) is suitable for roasting. Roasting is performed at about 1050°C, during which spodumene will go through a phase transformation from α-spodumene to β-spodumene. The α-spodumene is virtually refractory to hot acids.
