Lithium recovery from pretreated α ‐spodumene residue through acid leaching at ambient temperature
Article
  • Dec 2022
A novel alkaline hydrothermal approach for low‐temperature conversion of α‐spodumene into Li2SiO3 residue was proposed, providing a promising method for extracting lithium from α‐spodumene as a pretreatment process. This work proposed a systematical investigation for extracting lithium from the residue by acid leaching and preparing lithium carbona...

... Later on, the sparging of CO 2 further converts it to lithium bicarbonate (LiHCO 3 ) which is highly soluble and can be leached efficiently via H 2 SO 4 or HCl. 62 The process is quite simple and can successfully minimize the utilization of concentrated acids during roasting. However, the requirement of high roasting temperature directly increases the capital energy consumption. ...
