β-spodumene. The α-spodumene is virtually refractory to hot acids. As a result of the phase transformation, the spodumene crystal structure expands by about 30% and becomes amenable to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/
