To cope up with the supply–demand gap of lithium (Li) an essential energy element, the recycling of waste industrial effluent (generated after cobalt recycling from waste Li-ion batteries) is targeted. In industry, after the recovery of Co, Cu, Ni, and graphite from one ton of black cathodic material of Li-ion batteries about 8 m3 of waste effluent containing 5–10 g/L Mn and 1–3 g/L Li is generated. Systematic precipitation studies were carried out using saturated alkaline solution varying Eh/ pH of the effluent. Settling time 30 min and pH ~12 were found to be optimum conditions for maximum precipitation of Li (~90%) as salt. Precipitation studies for Mn/ Li with scientific validation were also carried out and discussed. The process developed has tremendous potential to be commercialized in industry after scale-up studies.
