At Guanma Machinery Hydrometallurgical Lithium Battery Recycling Plant that combine safe mechanical pretreatment with state-of-the-art hydrometallurgy to close the battery loop.
Rather than burning your profits, our wet chemistry approach gently dissolves and selectively separates lithium, cobalt, nickel, and manganese, transforming black mass into high-value, battery-grade precursors ready.
Hydrometallurgical Battery Recycling Plant Advantage
A standard smelting plant can recover cobalt and nickel but often fails to recover lithium economically. A standalone mechanical plant only produces a mixed powder (black mass) with limited market value.
A dedicated hydrometallurgical plant changes the game. By taking the black mass derived from shredded and separated batteries and processing it through a sequence of leaching, solvent extraction, ion exchange, and precipitation, we help you:
Unlock >90% recovery of Lithium
Reclaim lithium carbonate or lithium hydroxide rather than losing it in slag.
Produce Battery-Grade Sulfates
Manufacture cobalt sulfate, nickel sulfate, and manganese sulfate that command premium prices from cathode manufacturers.
Eliminate Harmful Off-gassing
Unlike fire-based methods, a hydrometallurgical reaction takes place in sealed, water-based environments at low temperatures, ensuring zero dioxin/furan emissions.
Complete Hydrometallurgical Battery Recycling Flow
To operate a profitable hydrometallurgical lithium battery recycling plant, the quality of your input material is critical. This is why Guanma Machinery offers mechanical lithium-ion battery recycling plant for the production of black mass.
We recently commissioned a high-capacity mechanical line in India designed to safely discharge, shred, and separate cylindrical and prismatic cells under an inert atmosphere. The output? High-purity black mass with copper and aluminum separation rates exceeding 99%. This clean, dry black mass becomes the ideal feedstock for the hydrometallurgical refining stage.
Step 1: Pre-Treatment & Black Mass Preparation
Safe Discharge & Crushing: Batteries are deep-discharged and fed into a nitrogen-protected dual-shaft shredder to prevent thermal runaway.
Pyro-Drying (Optional): A low-temperature (≤550°C) evaporation unit removes residual electrolytes and PVDF binder, exposing the active materials without melting the aluminum.
Gravity & Magnetic Separation: We achieve a Z-type air flow separation and magnetic sorting to isolate steel casings, copper foil, aluminum foil, and finally, the electrode powder.
Step 2: The Hydrometallurgical Core
Selective Acid Leaching: The black mass enters our specially formulated leaching tanks. Dissolve lithium, cobalt, nickel, and manganese while leaving most graphite and trace impurities in the solid residue.
Targeted Impurity Removal: Before recovering valuable metals, iron, aluminum, and copper traces are precipitated through processes and filtered out, ensuring the final product recovery rate 99.5%.
Solvent Extraction: Specific extractants) selectively bind with cobalt, nickel, and manganese in turn. We strip each metal into a concentrated aqueous sulfate solution.
Lithium Precision Recovery: After separating the transition metals, the raffinate rich in lithium is concentrated. we precipitate battery-grade lithium carbonate (Li₂CO₃) directly.
Step 3: Effluent & Circular Economy
Guanma hydrometallurgical plant integrates a closed-loop wastewater treatment system. Process water is neutralized, evaporated, and crystallized to recover sodium sulfate by-products.
Why choose Guanma Machinery as your manufacturing partner?
Our hydrometallurgical lithium battery recycling plant is a fully modular, turnkey installation.
Scaling Flexibility: Whether you are a startup handling 500 tons per year of black mass or an industrial plant processing 20,000 tons, our modular cells simply bolt together, reducing on-site civil work.
Automation: A centralized PLC system controls dosing, temperature, and phase separation, reducing reliance on highly scarce chemical engineers.
You can start with a mechanical lithium-ion battery recycling plant in India for the production of black mass to establish a feedstock base, and seamlessly upgrade to a full hydrometallurgical plant when your volume validates the CapEx.
