Jul 09, 2020 While ore grades vary widely, copper ores typically contain only about a half-percent, by weight, of the element itself thus, roughly 200 tons of ore are dug up, moved, crushed, and processed to get to one ton of copper. For rare earths, some 20 to 160 tons of ore are mined per ton of element. For cobalt, roughly 1,500 tons of ore are mined to ...
