India Reclaims Smartphone Minerals For Aviation
5.2
India's e-waste sector can supply aerospace-grade materials, industry leaders told India Today, highlighting that a ton of battery black mass yields 50–80 kg cobalt versus 1–2 kg from ore. Firms like Lohum, Attero and Metastable use hydrometallurgy or thermal reduction to recover lithium, cobalt, nickel and neodymium, but meeting 99.9% aerospace purity requires advanced metallurgy and significant industrial investment.
Key Points
- 1Recover high concentrations: 50–80 kg cobalt per ton from black mass, roughly 40× conventional ore yields
- 2Enable aerospace-grade materials but require 99.9% purity; trace contaminants can cause component failure
- 3Demand advanced hydrometallurgy or thermal methods and precision metallurgy to meet defence-grade standards
