Hydrometallurgical battery recycling at industrial scale

As battery recycling scales up globally, hydrometallurgical processing of black mass is increasingly required to perform under industrial conditions rather than in laboratory or pilot-scale environments. For plant operators, the key challenge is no longer whether hydrometallurgy works in principle, but how reliably and economically it can be operated while adapting to the realities of an evolving battery market.

This presentation addresses the core challenges that define hydrometallurgical battery recycling today. These include managing highly heterogeneous black mass compositions across different chemistries such as NMC, LCO and LFP; achieving consistently high recovery rates and battery-grade product quality; and ensuring stable, energy-efficient operation at relevant throughput levels.

It further examines how operational and environmental boundary conditions — including water management, residue handling and waste minimisation — influence plant design and long-term operability. Rather than treating these aspects as secondary considerations, the presentation shows why they must be integrated into the core process concept from the outset to enable reliable and scalable operation.

Drawing on experience from integrated end-to-end battery recycling projects and the design and realisation of hydrometallurgical plants, the speaker highlights what distinguishes future-ready recycling operations from theoretical or overly specialised approaches, and what plant operators should focus on when evaluating hydrometallurgical recycling concepts.
