“…Sharrat et al further explained the effect of temperature on the extraction efficiency. They suggested that the process is more feasible below 880 °C, because reaching the melting point of Li 2 SO 4 (859 °C) could give acceleration to sintering of lithium sulfate, which will ultimately lower the overall extraction efficiency . The amount of sulfuric acid added is another factor to be considered for optimizing the overall process efficiency.…”

Among all of the lithium-bearing minerals, spodumene possesses the highest theoretical lithium abundance. Since the 1990s, Australia, with the world's largest spodumene (LiAl(SiO 3 ) 2 ) reserves, has been producing lithium as a mineral concentrate rather than a refined product. Nevertheless, the country is now moving forward to fortify its processing facilities, aligning with the vision for greener energy. This review provides a comprehensive outlook on the current status of spodumene reserves and their processing facilities along with potential expansion in the future. Spodumene processing requires several metallurgical processes ranging from salt roasting to acid leaching. However, the conventional industrial practices for Li-extraction from ores result in excessive pressure on resources, energy, and waste management. Considering these factors as an indicator of a circular economy, the process of lithium extraction should be simplified. In such a context, different practices for Li-extraction from spodumene are exemplified by recent technological advancements. Afterward, strategies for decarbonization, waste management, and environmental aspects were provided, with a perspective of circular economy. This review is expected to serve as a reference for research and development for potential industrial applications in ore processing especially for spodumene.
