Black Mass Recycling Overview
The global shift toward battery-powered vehicles is accelerating, and with it, the need for sustainable solutions to recover critical raw materials. One of the key sources for these materials is black mass – the fine, metal-rich powder obtained from spent lithium-ion batteries.
Black mass contains valuable elements such as Nickel, Cobalt, Lithium, and Manganese, which can be recovered through hydrometallurgical recycling. This process includes several steps, such as mechanical pre-treatment, leaching, filtration, purification, solvent extraction, and crystallization.
Among these, filtration plays a role after the leaching phase, where undissolved solids like graphite and binders must be removed to ensure a clean solution for downstream metal recovery.
How Roxia SFP Supports Black Mass Recycling
• Operates autonomously with over 98% availability, minimizing manual supervision
• Efficiently removes undissolved solids like graphite after leaching
• Produces uniform filter cakes with low residual moisture, improving handling and metal recovery
• Fully enclosed and leak-proof design enhances safety when handling aggressive chemicals
• Supports predictive maintenance, reducing unplanned downtime
• Features self-cleaning cycles and advanced washing systems that extend filter cloth life
• Reduces environmental impact and utility consumption through optimized operation
