American Manganese Inc. and its R&D partner Kemetco Research Inc. announce that the leach section of its technology defining demonstration plant project has achieved over 99% extraction of lithium, nickel, cobalt, and manganese from lithium-ion battery production scrap. During the demonstration plant's leach stage testing, various operating parameters were investigated to determine the optimal conditions and collect data for ongoing commercial plant design and planning. Analysis of a range of leach data showed that the successful extraction results were achieved.
