The number of metal-containing waste streams resulting from electronic end-of life products, metallurgical by-products, and mine tailings to name but a few, is increasing worldwide. In recent decades, the potential exploit these as valuable secondary resources meet high demand critical economically important raw materials has become more prominent. this review, fundamental principles bio-based metal recovery technologies are discussed focusing on microbial metabolism-dependent metabolism-independent mechanisms sustainable alternatives conventional chemical methods. contrast previous reviews which have partially addressed topic, special focus will be given how can influence selectivity specificity recovery. While methods for show benefits in terms economic affordability, offer advantages efficiency environmentally friendliness. Modifications adaptations processes biosorption, bioaccumulation bioelectrochemical systems highlighted, further emphasizing application metal-binding peptides siderophores increase metals. Single solutions or mixtures with low complexity been studies reviews, does not reflect nature complex industrial effluents. Therefore, key challenges that arise when dealing polymetallic set optimizing recover metals efficiently selectively bio-leachates liquid streams.
