Guanma Machinery’s hydrometallurgy process battery recycling technology provides the answer – a closed-loop, high-efficiency system designed to recover >98% of critical metals from battery black mass. If you’re battling low recovery rates, environmental compliance hurdles, or inconsistent output quality, this detailed breakdown reveals why our hydrometallurgical processes for recycling spent lithium-ion batteries outperform traditional methods.
The Guanma Advantage: Precision Metal Liberation
Unlike pyrometallurgy (smelting) which loses lithium and generates emissions, our hydrometallurgy battery recycling process uses targeted chemical reactions in aqueous solutions to selectively extract metals. Here’s how our proprietary system works:
Step 1: Intelligent Black Mass Preparation
Our Black Mass Hydrometallurgy Machine integrates automated feeding and impurity removal
Precisely crushes and sieves material to optimal particle size (<200µm)
Removes plastics/aluminum foils via flotation, ensuring >95% pure electrode material
Key Benefit: Eliminates downstream contamination that disrupts chemical processes
Step 2: Targeted Leaching & Metal Dissolutio
Proprietary leaching reactors operate at controlled temperatures (60-90°C)
Customizable acid/oxidant blends (H₂SO₄/H₂O₂ or organic acids) dissolve metals
Real-time pH/ORP sensors optimize reaction kinetics
Key Innovation: Lithium recovery >99% (vs. <40% in smelting)
Step 3: Multi-Stage Solvent Extraction
Cascading mixer-settlers separate metals with surgical precision:
1. Extract cobalt
2. Separate nickel
3. Recover lithium
Automated reagent dosing maintains separation efficiency >99.5%
Competitive Edge: Achieves battery-grade sulfate purity (99.9%) in single pass
Step 4: Crystallization & Product Refinement
Lithium carbonate/nickel sulfate crystallization under vacuum
Cobalt oxalate precipitation with ammonium oxalate
Graphyte recovery via froth flotation from residue
Value Add: Directly produces saleable battery precursor materials
Step 5: Zero-Liquid Discharge System
Treats wastewater via reverse osmosis/evaporation
Recovers >95% process water for reuse
Solidifies residues into non-hazardous slag
