manganese mining and processing: everything you need to know

Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with land-based mining production. Once the ore is mined, it’s transferred to a processing plant for electrolytic processing or smelting
