This review adds to the public domain literature on the extraction of lithium from mineral ores. The focus is on the pyrometallurgical pretreatment of spodumene. Information on the phase transformation from α to β the heat treatment methods as well as the behavior of various compounds in the roasting processes are evaluated. Insight into the chemical thermodynamics of the baking
Kinetics and Mechanism of Lithium Extraction from αSpodumene in
Lithium extraction from αspodumene in a potassium hydroxide solution was proposed to provide a new green metallurgical process for spodumene concentrate. The structure of αspodumene could be destroyed directly by a KOH solution and new solidphase products of Li2SiO3 and KAlSiO4 were generated simultaneously. The total lithium extraction efficiency could reach of which was
Lithium extraction from βspodumene A comparison of keatite and
Oct 26 20221. Introduction. At present materials from lithiumbearing deposits are refined either to lithium hydroxide (LiOH·H 2 O) or lithium carbonate (Li 2 CO 3).The current industrial process of leaching spodumene with concentrated sulfuric acid to produce lithium hydroxide entails high energy and chemical consumption (H 2 SO 4 Ca(OH) 2 NaOH and CaCO 3 or Na 2 CO 3).
Comprehensive utilization of waste residue from lithium extraction
Aug 15 2021The lithium extraction process of spodumene mainly includes sulfuric acid method sulfate roasting method alkali method and chlorination roasting method etc. (Meng et al. 2021). Kuang et al.(2018) used Na 2 SO 4 to dissolve βspodumene and with addition of CaO to reach lithium extraction efficiency.
Revisiting the Traditional Process of Spodumene SpringerLink
A process of lithium extraction from spodumene ore has been patented as early as the middle of the twentieth century . This has led it to be the leader in the commercial mining of lithium rich minerals industry. The former process is still nowadays the most used by companies and is the base of many future spodumene projects.
