Manganese helps convert iron ore into steel, and chromium hardens and toughens steel. Furthermore, manganese is a critical ingredient of lithium-manganese-cobalt-oxide (NMC) batteries for electric vehicles. Although copper production is around one-third that of aluminum, copper has a key role in making modern life possible. The …
