Selective flotation separator for lithium battery black mass recycling

1.Product Introduction Ore Beneficiation Equipment

The Selective Flotation Separator is an intelligent sorting system specifically engineered for the recovery of Black Mass (active material powder) from decommissioned lithium-ion batteries. Utilizing ultrasonic-assisted flotation technology, the system achieves high-precision separation of electrode materials. The modular design integrates ultrasonic generators, multi-stage flotation cells, intelligent control systems, and material handling units. It enables the high-efficiency recovery of valuable metals such as Lithium Cobalt Oxide (LCO)and Lithium Iron Phosphate (LFP) from black mass while minimizing impurity entrainment. Its core advantage lies in the physicochemical synergy that facilitates the liberation and selective collection of electrode materials, serving as a critical unit in the battery recycling value chain.

2.Application Ore Beneficiation Equipment

• Decommissioned Battery Recycling: Separating Cobalt, Lithium, and Nickel from black mass to maximize resource circularity.
• Environmental Remediation: Minimizing battery waste in landfills and reducing the risk of heavy metal contamination.
• Material Regeneration & Reuse: Recovered metallic materials can be directly reintroduced into precursor production, lowering raw material extraction costs.
• R&D & Industrial Pilot Testing: Supporting lab-scale process optimization and providing empirical data for industrial-scale deployment.

3.Working Principle Ore Beneficiation Equipment

1. Ultrasonic-Assisted Liberation
The ultrasonic generator creates a cavitation effect, which strips away impurity layers from the surface of electrode materials. This enhances the differential hydrophobicity between the valuable active materials and carbon/impurities.
2. Multi-Stage Flotation Separation
• Stage 1: By adjusting pH levels and collector concentrations, the system prioritizes the recovery of hydrophobic minerals like Lithium Cobalt Oxide.
• Stage 2: Further isolates Lithium Iron Phosphate by precisely controlling froth thickness and pulp levels to minimize gangue entrainment.
• Stage 3: Scavenges the tailings to ensure the maximization of total metal recovery rates.
3. Intelligent Control
Utilizing AI algorithms, the system dynamically optimizes flotation parameters—such as ultrasonic frequency and reagent dosage—to adapt to the varying chemical compositions of different black mass batches.

4.Advantages Ore Beneficiation Equipment

• High Selectivity: The synergy between ultrasonics and flotation results in electrode material recovery rates exceeding 90%, with impurity content kept below 5%.

• Eco-Friendly & Energy Efficient: Reduces the consumption of chemical reagents and lowers wastewater treatment costs, aligning with Green Recycling standards.

• Modular Design: Supports rapid assembly, disassembly, and relocation, making it suitable for both laboratory research and industrial production environments.

• Data-Driven Optimization: Real-time AI analysis of flotation performance allows for dynamic parameter adjustments, significantly boosting separation efficiency.

• Superior Economics: Compared to traditional pyrometallurgical (smelting) methods, energy consumption is reduced by 40% and recovery costs are lowered by 30%.
