When a lithium-ion battery is discharged, dismantled and shredded, the fine powder left behind is called black mass — and it carries most of the battery's mineral value.
Concentrated mineral value
Black mass holds lithium, cobalt, nickel and manganese — the exact minerals needed to manufacture new cells. Recovering them domestically reduces dependence on virgin mining.
From powder to purified minerals
Through a hydrometallurgical pathway — pre-treatment, leaching, impurity removal, selective separation and crystallisation — black mass is refined back into battery-grade compounds, closing the loop.
