High purity nickel-cobalt hydroxide recovery

American Manganese Inc. has reported on the successful recovery of high purity (99.98%) nickel-cobalt hydroxide from the NCA cathode scrap material received from the tier-one lithium-ion battery company.

The laboratory studies were conducted by the Company’s independent contractor, Kemetco Research, to analyze the optimum recycling conditions and produce recycled material for the customer’s evaluation.

“We designed the process with the goal to produce recycled battery products that could be seamlessly integrated into the re-manufacturing of battery cathodes using minimal processing steps,” said Norm Chow, President of Kemetco Research.

After continuous improvement and optimization, American Manganese’s RecycLiCoTM patented process achieved an even higher purity than the previously reported purity results (99.94%) during stages 3 and 4 of Pilot Plant project.

The RecycLiCoTM patented process is a closed-circuit hydrometallurgical solution for recycling lithium-ion battery material. American Manganese has completed testing of the Pilot Plant project and aims to begin engineering design and economic analysis of a 3-5 tonne per day commercial demonstration plant for 2020; following the completion of testing for tier-one companies.

The process provides high extraction of cathode metals, such as lithium, cobalt, nickel, manganese, and aluminium at battery-grade purity, with minimal processing steps.
