Here, we demonstrate that synergic SX systems containing a βdiketone (HPMBP, HTTA or HDBM) and Cyanex 923 are highly selective for magnesium extraction over lithium (separation factor α > 1,000) The extracted magnesium and lithium complexes have the stoichiometry of [Mg∙A 2 ∙(C923) 2 ] and [Li∙A x ∙(C923) 2 ] ( x = 1,
Hydrometallurgical processing of magnesium minerals A
Common steps in primary magnesium production from ore (for enduse as a metal alloy or as a compound) is the mining of the ore, followed by mineral beneficiation through magnetic separation of Fe 3 O 4 and other techniques (Ağrılı 2019), followed by the extraction of a magnesiumbearing mineral (eg magnesite), and then conversion into
