“…Constant low pH is, however, also important in metal bioleaching from waste. According to our results as well as published data [30,31] it is evident that iron plays an important role not only in bioleaching of metals from sulphide ores but also in bioleaching of metals from waste where they occur in metallic or oxidic form. Similarly as in nature, e.g.…”

The role of iron in metal-bearing waste bioleaching was studied. Four various types of waste (printed circuit boards (PCBs), Ni-Cd batteries, alkaline batteries and Li-ion batteries) were treated by bioleaching using the acidophilic bacteria A. ferrooxidans and A. thiooxidans (separately or in mixture). Role of main leaching agents (Fe 3+ ions or sulphuric acid) was simulated in abiotic experiments. Results showed that oxidation abilities of Fe 3+ ions were crucial for recovery of Cu and Zn from PCBs, with the efficiencies of 88% and 100%, respectively. To recover 68% of Ni from PCBs, and 55% and 100% of Ni and Cd, respectively, from Ni-Cd batteries both oxidation action and hydrolysis of Fe 3+ were required. The importance of Fe 2+ ions as a reducing agent was showed in bioleaching of Co from Li-ion batteries and Mn from alkaline batteries. The efficiency of the processes has increased by 70% and 40% in Co and Mn bioleaching, respectively, in the presence of Fe 2+ ions. Based on the results we suggest the integrated biometallurgical model of metal-bearing waste recycling in the effort to develop zero-waste and less energy-dependent technologies.

“…There are also a range of microbially produced chelates that might be applied to enhance solubilization of target metals; for example, Acidithiobacillus thiooxidans and Aspergillus niger have been tested for application to the leaching of steel slag [62], while Cheng et al [63] examined bioleaching from Pb/Zn smelter slags. A recent and thorough review on bioleaching of solid waste and secondary resources was conducted by Lee and Pandey [64]. Table 2 shows examples of (bio)hydrometallurgical systems from the literature which might be useful for in situ leaching of candidate waste repositories.…”

Wastes and the waste repositories in which they reside are becoming targets for resource recovery, both for legacy wastes and for future waste arisings as part of a desire to move toward a circular economy. There is an urgent requirement to explore concepts for practicable technologies that can be applied to these ends. This paper presents a synthesis of concepts concerning in situ technologies (developed from mining and contaminated land remediation industries) that have enormous potential for application to technospheric mining. Furthermore, potential target waste streams and their mineralogy and character are presented along with a discussion concerning lixiviant and metal capture systems that could be applied. Issues of preferential flow (critical to the success of in situ techniques) and how to control it with engineering measures are discussed in detail. It is clear that in situ recovery of metals from anthropogenic ores is a novel technology area that links new sustainable remediation approaches for contaminated materials and technospheric mining for closing material loops, and warrants the further research and development of technologies applicable to major waste streams.

“…Most process developments are chemical rather than biochemical, as evidenced by the numbers of publications found in literature searches using the terms: "laterite AND leach*" (766) against "laterite AND bioleach" (40), "manganese dioxide" AND leach*" (576) against "manganese dioxide AND bioleach*" (15), or "copper silicate AND leach" (7) against "copper silicate AND bioleach" (1). As a further example, in a recent review [312], commercial processes and prospective processes for nickel laterites were described and critically assessed; none of them utilised microorganisms.…”

This review has as its underlying premise the need to become proficient in delivering a suite of element or metal products from polymetallic ores to avoid the predicted exhaustion of key metals in demand in technological societies. Many technologies, proven or still to be developed, will assist in meeting the demands of the next generation for trace and rare metals, potentially including the broader application of biohydrometallurgy for the extraction of multiple metals from low-grade and complex ores. Developed biotechnologies that could be applied are briefly reviewed and some of the difficulties to be overcome highlighted. Examples of the bioleaching of polymetallic mineral resources using different combinations of those technologies are described for polymetallic sulfide concentrates, low-grade sulfide and oxidised ores. Three areas for further research are: (i) the development of sophisticated continuous vat bioreactors with additional controls; (ii) in situ and in stope bioleaching and the need to solve problems associated with microbial activity in that scenario; and (iii) the exploitation of sulfur-oxidising microorganisms that, under specific anaerobic leaching conditions, reduce and solubilise refractory iron(III) or manganese(IV) compounds containing multiple elements. Finally, with the successful applications of stirred tank bioleaching to a polymetallic tailings dump and heap bioleaching to a polymetallic black schist ore, there is no reason why those proven technologies should not be more widely applied.
