Extraction of lithium from spodumene Murdoch

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.
