Lithium Extraction From Spodumene

Processing Spodumene by Froth Flotation for Lithium Extraction

Extracting Lithium from its Ore The problems of spodumene mineral dressing depend on the amount of ore deposit, weathering and presence of associated gangue minerals. Weathered mineral surfaces must be thoroughly cleaned for selective flotation. Slimes interfere with selective flotation and also consume expensive reagents.

Commercial Lithium Production and Mining of Lithium

Extraction from spodumene is expensive but fast, while processing of clay is not yet commercially proven at scale. There are disruptive new lithium extraction technologies being looked at including leaching, solvent extraction, geothermal extraction and electrolysis, but the findings are too inconclusive to be used commercially.

What is Lithium Extraction and How Does It Work?

Hard rock / spodumene lithium extraction While accounting for a relatively small share of the world’s lithium production, mineral ore deposits yield nearly 20 tons of lithium annually. Well over 100 different minerals contain some amount of lithium, however, only five are actively mined for lithium production.

Spodumene Makes A Comeback in the Rush for Lithium

Known for its high lithium content, spodumene is the most widely exploited mineral source of lithium. Other lithium-bearing pegmatite silicates include lepidolite and petalite. At one time, spodumene was the primary source of lithium production, but the industry transitioned to extracting lithium from brines because of the significantly lower ...
