American Manganese pilot plant testing successfully completed

The pilot plant testing program performed by Kemetco Research has been successfully completed. The work has confirmed the technical viability of the American Manganese’s patent pending hydrometallurgical manganese extraction and EW circuit on a semi-continuous operation basis of the overall flowsheet. The process is designed to recover manganese from lower grade manganese resources in an energy efficient manner with low water use, thus providing significant environmental benefits compared to the conventional recovery process which is energy intensive based on high grade resources.
