Nowadays, the demand for certain metals can shift on relatively short notice. The reason being, for example, that electric cars require three to four times as much copper as cars with combustion engines; Car manufacturers like BMW replace large amounts of steel previously used for the car bodies with fibreglass-reinforced plastics; large battery packs, depending on which kind of battery technology, require significant amounts of lithium, cobalt, graphite, and nickel. Therefore with industry and technology driven changes, the demand for certain materials make it necessary to develop new mineral deposits and build new production facilities.
