Gcse Chemistry Phytomining + Bioleaching Flashcards

- Both Phytomining, and bioleaching enable us to economically extract metals from low - grade ores. ^ Important, as the Earth's resources of metal ores are limited ( scarce). - Both phytomining, and bioleaching, do not involve digging, transporting and disposing of large amounts of rock, unlike traditional mining of metal ores.
