If we broke open all the newest phones and split them into their component parts, that would produce around 85,000 kg of gold, 875,000 of silver, and 40,000,000 of copper. How did this precious cache get into our phones--and can we reclaim it? Kim Preshoff investigates the sustainability of phone production.
