Recovery of lithium from Uyuni salar brine - ScienceDirect
2012-4-1 The final precipitation of lithium at 80–90 °C produced a high purity (99.55%) and well crystalline lithium carbonate. Highlights We developed a new process for recovering lithium from Uyuni salar brine. Mg, Ca, B and sulphate were removed by lime precipitation. Residual Ca–Mg was removed by oxalate. A 99.55% lithium carbonate was produced.

2018-1-1 A combined process has been developed for recovering cobalt and regenerating cathode material from leach liquor of spent LiCoO 2 batteries. Cobalt of 98% can be selectively separated from leach liquor using ammonium oxalate of 1.15 (mole ratio) at pH of 2.0, 55 °C, and 40 min. Kinetics analysis indicates that precipitation of cobalt is controlled by a combination of surface chemical
