Lithium Production Processes

The gypsum–limestone process was later utilized by Büyükburç and Köksal 69 to extract lithium from a boron clay containing 0.2% Li. A mixture of the clay with these additives was sintered at 915 °C for 110 min and the calcine was then subjected to water leaching at room temperature, resulting in approximately 88% Li recovery.
