  • Processes for recovering lithium values from lithium-containing brines
    Patent number: 12570537
    Abstract: Producing high purity lithium solution from a source brine containing at least 1 mg Li/kg brine, preferably 10 mg/kg, more preferably 25 mg Li/kg brine; treating the source brine, if necessary in pretreatment steps; processing the treated brine in a lithium adsorption step; after the adsorption step, desorbing the adsorbed lithium in a desorption step; after the desorption step, treating the desorption effluent in an enrichment step. Specified optional steps and new features can be used to increase lithium concentrations and purity.
    Type: Grant

  • Platform and system for crystal nucleation and growth
    Publication number: 20050155542
    Abstract: A method for growing crystals comprises removing solvent from a first plurality of solutions of a compound simultaneously and at substantially the same rate, to form a solid; and removing solvent from a second plurality of solutions of the compound simultaneously and at different rates, to form a solid. The first plurality of solutions contain different concentrations of the compound, and the second plurality of solutions contain substantially the same concentration of the compound.
