There have been experiments to extract uranium from sea water, but the yield has been low due to the carbonate present in the water.

Because the dibutyl phosphate ligands are acidic, it will now be possible to extract uranium by an ion exchange liquid-liquid extraction mechanism rather than only by a solvation mechanism.

She selectively extracted uranium from ore samples to create purified uranium preparations and established a half-life for ionium.

This older method of extracting uranium from its uraninite ores has been replaced in current practice by such procedures as solvent extraction, ion exchange, and volatility methods.
