The conventional process of lithium extraction from α-spodumene requires high-temperature calcination to transform α-spodumene into β-spodumene, and concentrated acid roasting followed by water leaching. This study proposed the direct preparation of water-soluble lithium salts from α-spodumene by roasting with different …
Heat-treatment of spodumene concentrate at 1323 K (1050 °C) for 30 min in a rotary kiln yielded a successful decrepitation. Particle size decreased from 2 cm to less than 425 µm for 80% of the initial mass. X-ray analysis of both fractions did not reveal the presence of α-spodumene or γ-spodumene. The coarse fraction was ground to less …
