LFP Battery Black Mass Hydrometallurgical Recycling Machine: Among the recycling technologies for spent LFP batteries—hydrometallurgy, pyrometallurgy (dry process), and bio-recovery—hydrometallurgy is the most effective method. It specifically targets the recovery of key elements such as Al, Fe, and Li from spent LFP batteries.
Hydrometallurgy Recycling Process
1. Pretreatment
Discharge, dismantle, crush, and sort spent LFP batteries. Recycle plastics and iron casings from dismantled components. Separate cathode materials (e.g., aluminum foil, binders, separators) via magnetic sorting to obtain phosphate iron lithium (LFP) cathode powder.
2. Leaching
Dissolve valuable metals (Li, Fe, P, etc.) from the black powder into a liquid phase using acidic/alkaline solutions.
3. Purification & Impurity Removal
Remove impurities (Fe, Al, Ca, Mg, etc.) from the leachate to ensure lithium purity.
4. Lithium Precipitation
Precipitate lithium salts (e.g., lithium carbonate) from the purified solution.
5. Concentration & Crystallization
Concentrate and crystallize the solution to recover cobalt/nickel salts (if present) and further refine lithium salts or byproducts.
