Webβ-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/ WebSPODUMENE Chemwatch: 37118 Version No: 4.1.1.1 Safety Data Sheet according to WHS and ADG requirements Issue Date: 27/06/2024 Print Date: 04/09/2024 S.GHS.AUS.EN …

WebSpodumene ore naturally occurs in the crystal structure of monoclinic alpha form (α-form). In order to extract lithium from the ore via the leaching process, however, the ore’s crystal structure must be in the tetragonal beta form (β-form). ¹ This conversion is achieved through decrepitation, or the shattering of the crystal structure. WebAll processes of recovery of lithium values from spodumene or lepidolite involve high temperature reactions. A typical process would involve two roasting kilns. In the first kiln the spodumene is heated to 1100°C. for conversion to the softer beta phase. The beta crystal is then finely ground to between 100 to 200 mesh, in
