The first method is called bioleaching, which uses bacteria to produce a leachate solution containing copper ions that are then purified using electrolysis. The second method is called phytomining, which involves using specific plants to absorb copper ions through their roots, and then burning them to produce ash. The ash is then treated with acid to produce a leachate from which copper is displaced and purified using electrolysis. The video highlights the advantages of these methods, including the extraction of metals from low-grade ores and mining waste, as well as providing a source of energy from burning the plants used in phytomining. However, the video also points out that only small quantities of metals are produced over a long period of time, which can be a disadvantage.\n
