Evaluate the Use of Phytomining and Bioleaching in Metal

We can extract the copper from this with electrolysis or by a displacement reaction with scrap iron: Cu 2+ (aq) + Fe(s) → Cu(s) + Fe 2+ (aq) Like phytomining, bioleaching is a useful method for extracting metals from lowgrade ores This is particularly important for copper, where highgrade ores are increasingly rare It also uses lessPhytomining How It works When the plants are burned, the ash that is produced contains these copper compounds Then, the copper will be extracted from the leachate by electrolysis or scrap iron Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate What happens during bioleaching? BioleachingHow are metals extracted with bioleaching?
