Rubidium and Cesium Recovery from Brine Resources

In this paper, the methods for rubidium (Rb) and cesium (Cs) recovery from brines including salt lake brine, geothermal water and concentrated seawater were summarized, and the main problems existed were also pointed out. More details for Rb and Cs recovery from salt lake brines through fractional precipitation, ion exchange and solvent extraction were discussed, and the new trend for Rb and Cs recovery in the future were also carried out.
