Abstract

Methods and apparatus for integrated alkali metal extraction are disclosed. Various exchange media are used to separate a chosen alkali metal, usually lithium, from a source stream and render the alkali metal into a product. In some cases, absorption/desorption processes, using solid and/or liquid absorption media, are used to purify a brine stream into a concentrate stream having elevated concentration of the desired alkali metal. Various processes, which may include use of liquid absorbents, electrochemical processing, centrifugation, evaporation, electrical mixing and separation, or combinations thereof, are used to separate the chosen metal from the source, and aqueous streams are recycled among the processes to facilitate the various separations.
