Abstract: Methods of recovering precious metals and/or lithium from unconventional feed water sources. In approaches, the methods use a combination of one or more of ultrafiltration, nanofiltration, and/or reverse osmosis membranes. The unconventional feed water source may be salt lake brines, coal-fired plant flue-gas scrubber blowdown water, concentrated brine from desalination of seawater, high-salinity brines, and the like sources. The recovered precious metals may include gold tetrachloride, gold sulfate, silver tetrachloride, silver sulfate, rate earth elements, lithium, or mixtures thereof.
