So far, bioleaching has been applied to extract zinc (Zn), cobalt (Co), copper (Cu), nickel (Ni), lead (Pb), gold (Au), and arsenic (As) from minerals in the industry [102,103]. For example, bioleaching of copper can achieve a higher than 90% recovery rate, and each year approximately 20% of global copper is produced through bioleaching [ 104 ].
