The recovery of metals present in low-grade ores and waste of electrical and electronic equipment (WEEE) is essential for the development of new technologies and the supply of existing production
chains. Conventional recovery processes are energy-intensive, non-selective towards some metals,
and mostly they are not eco-friendly. Thus, biomining appears as an interesting alternative, because
microorganisms are used to promote the bioleaching or bio-oxidation of metals present metal-rich
materials under mild conditions of pressure and temperature. Biomining can be industrially applied,
but it still needs some improvement such as diminishing the time required, the robustness and reliability
of biological systems, and the optimization of process parameters. In this review, we present the current
frontiers in biomining scale-up and some future perspectives, a brief discussion about microorganisms
involved in the mining processes to several ores, and biochemical reaction mechanisms in bioleaching
and bio-oxidation processes.
