Extraction of lithium from spodumene Murdoch University

The highest extraction of 98% was achieved after roasting at 250 °C for 1 hour with 80% excess acid to the stoichiometry of the reaction of spodumene and sulfuric acid. Elongated roasting, roasting at temperatures close to boiling point of the acid and very high amount of excess acid negatively affected Li extraction.

What is Lithium Extraction and How Does It Work?

Jul 31, 2018· Once the lithium extraction process is complete, the remaining brine solution is returned to the underground reservoir. 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.

Commercial Lithium Production and Mining of Lithium

Aug 21, 2020· In contrast to salar brine sources, extraction of lithium from spodumene, lepidolite, petalite, amblygonite, and eucryptite requires a wide range of processes. Because of the amount of energy consumption and materials required, lithium production from mining is a much more costly process than brine extraction, even though these minerals have a higher lithium content than the

Extraction of lithium from primary and secondary sources

Dec 01, 2014· Lithium extraction from primary resources such as ores/minerals (spodumene, petalite and lepidolite) by acid, alkaline and chlorination processes and from brines by adsorption, precipitation and ion exchange processes, is critically examined. Problems associated with the exploitation of other resources such as bitterns and seawater are highlighted.
