Li Extraction from a-Spodumene Concentrate via Carbonizing Calcination

Li Extraction from a-Spodumene Concentrate via Carbonizing Calcination

The conventional lithium extraction method involves the calcination of a-spodumene at 1050 °C so that it can be converted to the more-reactive b-spodumene and then a sulfuric acid roasting step at 250 °C. Lithium is finally extracted via leaching with water. This method is energy-intensive, leading...
