摘要： This invention relates generally to a process for selective adsorption and recovery of lithium from natural and synthetic brines, and more particular to a process for recovering lithium from a natural or synthetic brine solution by passing the brine solution through a lithium selective adsorbent in a continuous countercurrent adsorption and desorption circuit.

摘要： This invention relates generally to a system and process for recovery of select minerals and lithium from a geothermal brine. The system and process are configured for the sequential recovery of zinc, manganese, and lithium from a Salton Sea Known Geothermal Resource Area brine. The system and process includes: 1) an impurity removal circuit; then 2) a continuous counter-current ion exchange (CCIX) circuit for selectively recovering lithium chloride from the brine flow and concentrating it using a CCIX unit; and then 3) a lithium chloride conversion circuit for converting lithium chloride to lithium carbonate or lithium hydroxide product.
