Lithium Production Processes
Limestone was usually chosen as a cheap additive for roasting of lepidolite. 43., 54., 55., 56. In a process patented by Mazza et al., 43 a mixture of lepidolite, limestone, and water was fed to roasting at 900 °C for 2 h. The calcine was thereafter immediately quenched to release lithium, resulting in a lithium extraction of ∼80%.
