# MiniMines Claims High-Purity Mineral Recovery From Used Batteries 2026-08-06T11:16:41+00:00 | Technology | Indian Opinion Desk Corroboration: 2 independent outlets Clean-tech company MiniMines says its patented Hybrid-Hydrometallurgy process can recycle batteries across chemistries, including those used in phones, laptops, drones and electric vehicles. The company says it recovers lithium, cobalt, nickel and copper at a 96% recovery rate and above 99% purity. It also claims the process produces no solid, liquid or gaseous waste. MiniMines says it is building a critical mineral refining complex on 40 acres provided at subsidised rates by the Karnataka government. It expects processing capacity to reach about 45,000 metric tonnes a year by the end of 2028. The company said India’s battery manufacturing is expanding, but precursor cathode materials remain a missing part of the local supply chain. ## Coverage - hindustantimes.com Tags: battery recycling, critical minerals, electric vehicles, Karnataka, lithium Canonical: https://indianopinion.org/minimines-claims-high-purity-mineral-recovery-from-used-batteries/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
