Extraction of lithium from spodumene Murdoch University

Spodumene is an important source of lithium, a key element of Li-ion batteries used in mobile communication and entertainment devices, hybrid and all electric cars and electric bikes. Spodumene forms three different crystal structures, the naturally occurred α- spodumene, and y and β-spodumene which are the products of heat treatment at 700 to 1100 °C.

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.
