“…investigated the biotreatment of sulphide mine-wastes using bioleaching in the presence of Acidithiobacillus ferrooxidans. The results represented that the formation of biogenic jarosite during bioleaching led to a stable compound for the mine-waste less prone to dissolution in the acidic medium of mine tailings compared with the current techniques [2]. successfully performed the minimization of metals leaching from mine tailings due to the native bacteria activity, leading to the generation of a passivation layer.…”

“…The micron-sized analysis of the treated soil shows the generation of small particles of biogenic jarosite as a protective structure covering the toxic tailings soil. Also, the nano-scale probe demonstrates the overlapping of surface passivation particles on pyrite and sulphide minerals [9] (Figure 1).…”

“…In bioleaching, microbes mediate the leaching of trace elements from soil [1]. The application of Acidithiobacillus bacteria for heavy metals bioleaching from contaminated soil was investigated in recent works [2,3]. Manganese is recovered from its sources by bioleaching, which converts MnO2 into the low valence of Mn compounds [4].…”

Bioleaching can be used for the treatment of toxic elements in sulphide mine-wastes as a newly developed, green and cost-effective technology. The bacterial activity causes the remarkable dissolution of elements compared with chemical methods. Researchers have employed bioleaching for the separation of trace elements from different sources. However, the transfer of toxic elements from contaminated solid wastes to the aquatic ecosystem can be minimized by the production of a biogenic passivation layer. It has resulted in a new perspective of microbial leaching application for the remediation of toxic soils. In this paper, bioleaching-based techniques for a reduction in the environmental pollution of mine tailings were reviewed.

“…Alternatives for chemolithoautotrophically bioleaching have to be found, because like traditional metallurgical leaching, huge tailing ponds with highly acidic liquid waste are needed for large-scale heap or dump bioleaching. This acid mine drainage has a heavy environmental impact [26,27].…”

The usage of biotechnological molecules and processes is an indispensable part of the resource technology research. The development of novel biomolecules therefore needs to be adapted to the existing applicational conditions and biological processes are to be examined. Novel biosorbents may not only contribute to future applications but can be of further used, e.g. to better understand the interaction of known metal- and metalloid-interacting biological molecules and materials. This review highlights biotechnological approaches published so far for bioremediation as well as metal recovery with a special spotlight on cobalt, nickel and arsenic.

Mines result in land use and land cover (LULC) change due to degradation of natural resources and establishment of new infrastructure for ore extraction and beneficiation. The present study was carried out to, with objectives, (1) characterize LULC change (from 1975 to 2017) in Khetri copper mine region, (2) spatial distribution of pollution indices and (3) spectral response of elemental concentration of soil and groundwater using Landstat and ASTER satellite data. The study was designed to fulfil the objectives and for the same NDVI values were calculated for LULC classification and generated maps were analyzed for landscape pattern. Spatial distribution of pollution indices calculated using geochemical data of soil and groundwater was plotted to understand the impact of contamination on landscape pattern. The correlation of spectral response of Landstat bands with heavy metals concentration was plotted to assess their possible use in quantification of heavy metals. Results show constant increase in settlements, mines and open area while vegetation cover has decreased. Landscape and class level metrics (number of patch, patch density, aggregation index and landscape shape index) indicate increase in the fragmentation of landscape in recent years. Shannon’s Evenness Index indicates increase in uniformity in landscape and it is attributed to loss of vegetation and agriculture patches. Pollution indices, Pollution Load Index for soil is high near the overburden materials and Index of Environmental Risk (IER) and Contamination Index for ground water is high near abandoned mines. Spectral bands 5 and 6 (SWIR 1) show significant negative correlation, and 9 (Cirrus) shows significant positive correlation with metal concentration in soil and water suggesting the possible use of remote sensing in assessment of metal concentration at ground level. Thus, it can be concluded that mines significantly influence the landscape pattern and remote sensing could be used for the assessment and predication of heavy metal contamination at broader scale in a cost-effective way.
