MiniMines Cleantech secures Indian patent for hybrid hydrometallurgy battery recycling technology

MiniMines Cleantech Solutions, an end-to-end solutions provider for end-of-life lithium-ion batteries, has been granted a patent by the Indian Patent Office for its Hybrid Hydrometallurgy (HHM) technology. The patented process enables the efficient recovery of critical minerals from energy storage devices and electronic waste, including end-of-life lithium-ion batteries, irrespective of their chemical composition, size or shape.

The patented HHM technology integrates multiple recovery techniques into a unified hydrometallurgical process, enabling the efficient extraction of valuable critical minerals from end-of-life lithium-ion batteries.

According to the company, the process enables the recovery of high-purity materials, including lithium, cobalt, manganese, aluminium, copper and nickel, along with spherical graphite with up to 99% purity, while maintaining a low environmental footprint.

“Designed and developed in India, the technology addresses a growing need for sustainable and resource-efficient battery recycling solutions as the adoption of electric vehicles and energy storage systems accelerates globally,” said Arvind Bhardwaj, Founder & CTO, MiniMine. The patented process has already been successfully deployed and validated at MiniMines’s commercial facility.
