“…18 To improve this disadvantage, lab-scale experiments were performed for the metal recovery from the slag. Dang et al 42 and Li et al 43 added calcium chloride and sodium sulfate, respectively, to the smelter slag and roasted the mixture at 800 °C for 1 h to convert the insoluble lithium into a water-soluble salt. In this process, the leaching rate of lithium could reach 90%.…”

The rapid development of the electric vehicle industry has spurred the prosperity of the lithium ion battery market, but the subsequent huge number of spent lithium ion batteries (SLIBs) may bring severe environmental problems. Because of the advantages of low raw material requirements and little waste liquid production, pyrometallurgical technology is suitable for recycling SLIBs in large-scale industrial applications. After decades of research, the practice of pyrometallurgical technology in related fields has developed a lot. There are three essential components of SLIBs, namely, binders and electrolytes, cathode, and anode. This article summarizes the development of pyrometallurgical technologies in dealing with these three parts and analyzes the strengths as well as weaknesses of each technology. Moreover, it reveals the evolution and the challenges of pyrometallurgical technology in recycling SLIBs. A high-value utilization with the characteristics of an overall resource utilization of waste batteries is a promising development direction for pyrometallurgical technology.

“…Lastly, the process results in the generation of environmentally green waste. These advantages call for a closer look at chlorine for beneficiating lithium ores, however, it has attracted little attention and few literature articles have been written about it [41][42][43][44][45][46].…”

This review adds to the public domain literature on the extraction of lithium from mineral ores. The focus is on the pyrometallurgical pre-treatment 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 process is evaluated using HSC Chemistry software up to 1200 °C. It was observed that the alkaline, sulfation, chlorination (using Cl2 and CaCl2), carbonizing (to form Li2CO3) and fluorination processes were feasible either throughout or at a point within the temperature range considered. Chlorination using KCl and carbonizing to form Li2O are the processes found to be nonspontaneous throughout the temperatures considered.

“…Therefore, the recovery of these valuable components from spent LIBs has high economic and environmental benefits. [12][13][14] Recently, the recycling process of spent LIBs has mainly included hydrometallurgy, 15,16 pyrometallurgy, 17,18 bioleaching 19 and combination methods. [20][21][22][23] In a typical hydrometallurgy, leaching is a key step that determines the efficiency of metal recovery.…”
