What is Spodumene? Spodumene is a pyroxene mineral that is typically found in lithium-rich pegmatites.It is usually associated with other lithium minerals such as lepidolite, eucryptite, and petalite.Spodumene has a chemical composition of LiAlSi 2 O 6 but small amounts of sodium sometimes substitute for lithium.. Throughout most of the 20th century, spodumene was the most important ore …

Extraction of lithium from primary and secondary sources ... 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.

AMG can recover lithium-bearing materials from the existing and future tailings at its profitable tantalum operations at Mibra, with the ore extraction and crushing costs absorbed by the Tantalum operations. AMG has successfully operated a lithium pilot plant since 2010, with more than 2.8 million tons of spodumene feed stock having been extracted.

Extraction of Li from spodumene using chlorination has been proven effective due to the high reactivity and strong affinity of chlorine and the formation of lithium chloride (LiCl) that can be easily dissolved in water (Barbosa et al., 2013, Table 5). To date, chlorine gas (Cl 2) and chloride have been used as chlorinating agents. No matter ...
