Black Mass Refining Plant

High-Value Recovery from Black Mass

Black mass — the valuable concentrate obtained after mechanical processing of end-of-life lithium-ion batteries — contains critical metals like lithium, nickel, cobalt, and manganese. Refnic’s hydrometallurgical refining technology efficiently extracts these metals into battery-grade salts, closing the loop in the battery supply chain and reducing dependence on imported raw materials.

Why Refnic Black Mass Refining?

01

Superior Recovery Rates

Achieves over 95% recovery for nickel, cobalt, and manganese, and significantly higher lithium recovery compared to conventional pyrometallurgical or basic hydrometallurgical routes.

02

Battery-Grade Purity

Produces high-purity lithium carbonate, nickel sulfate, cobalt sulfate, and manganese sulfate directly suitable for new cathode manufacturing — meeting stringent battery industry specifications.

03

Flexible Chemistry Handling

Our modular flowsheets efficiently process mixed NMC, LFP, NCA, and other battery chemistries without major process changes, giving operators long-term flexibility.

04

Lower Environmental Impact

Operates at mild temperatures with reduced energy consumption, lower CO₂ emissions, and optimized reagent recycling compared to high-temperature smelting methods.

05

Modular & Scalable Design

Containerized and skid-mounted modules allow faster project execution, lower upfront capital, and easy capacity expansion as black mass availability grows.

Our Black Mass Refining Process

Leaching → Impurity Removal → Selective Solvent Extraction → Precipitation / Crystallization → Final Purification. Each step is optimized for maximum selectivity, high recovery, and minimal waste generation.

Strategic Value for India

Domestic black mass refining is critical for reducing import dependence on critical minerals, meeting EPR obligations, and building a self-reliant battery ecosystem. Refnic’s technology enables recyclers and battery manufacturers to capture maximum value from black mass while complying with stringent environmental and quality standards.
