Introduction The application of bioleaching of metal sulfides (MS) and its understanding have evolved over the last decades. The mobilization of metal cations from often almost insoluble minerals in ores by biological acidification, oxidation, and complexation processes is referred to as bioleaching, and its application is termed …

India has bountiful reserves of Coal, Iron, Manganese, copper and Lead-Zinc. Mining the same causes generation of a huge volume of waste. Out of the total generated waste, 4.5 million tons are hazardous [7]. Managing waste from mining sulfides, Uranium & Coal poses a potential threat to the ecosystem (tailings, especially) and is an arduous task.
Microbes are playing increasingly important roles in commercial mining operations, where they are being used in the "bioleaching" of copper, uranium, and …
Bioleaching (or biomining) is a process in mining and biohydrometallurgy (natural processes of interactions between microbes and minerals) that extracts valuable metals from a low-grade ore with the help of …
Function-based mining of microbes from nature has traditionally employed a 'culture-first, screen-second' strategy: cells are exposed to a particular culture condition until individual ...
Activeness such as mining, electroplating, metallurgical smelting actions, and agriculture have contaminated wide areas of the world. Microbial resistance and tolerance toward pollutants, particularly heavy metals, are absolutely vital in the bioremediation processes as required microorganisms such as bacteria, fungi …

The results implied that soil catalase activity in NSA and ureases activity in the 20–40 cm soil layer of NSA and OSA were significantly enhanced after vegetation restoration, and that long-term plant restoration could improve soil fertility and soil microbial community diversity in coal mining areas. Vegetation restoration is an available way to …
1. Introduction. At its core, desertification is the insidious transformation of once-productive land into arid, degraded expanses. It manifests predominantly in arid, semi-arid, and dry sub-humid regions, where climatic conditions and anthropogenic activities converge to alter ecosystems dramatically (Yu et al., 2022).The consequences of …

Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes …
Microbial genome mining is an important emerging technology to discover new and novel natural products (NPs) for drug discovery. 1–4 The genome mining concept stems from the seminal observations of

Redundancy analyses suggested that alfalfa revegetation and sludge biochar amendment significantly affected soil microbial community structure, and additive effects on the improvement of soil physicochemical properties as well as increases in the richness and diversity of bacterial and fungal communities were detected. Long-term unregulated …
Harnessing microbes to do mining work is called biomining, or sometimes bioextraction or bioleaching. The strategy has been most extensively studied for copper and gold: Colorado-based mining consultant Corale L. Brierley estimates that 10 to 15% of copper and 5% of gold worldwide ...

Continuous application of phosphate (P) mineral to soil renders apatite addition during each crop growing season which is of great concern from a sustainable agriculture viewpoint. Use of efficient phosphate solubilizing microbes (PSB) is one of the most effective ways to solubilize this apatite mineral in the soil. The current study …

Microbes catalyse the reoxidation of the ferrous ion to ferric (reaction 2), which regenerates the major reactive oxidant in the leaching process, and sulfur to sulfuric acid …
The use of a passive mine drainage treatment system was effective for wastewater and acid-mine drainage with elevated concentrations of arsenic and chromium (Fig. 6). The results of Ozawa and Cohen [26] are in contrast to those of Walker and Hurl [27] who reported an increase in As and no change in Cr in a stormwater treatment wetland.
Biomining is the use of microorganisms in the recovery of metals from ores. During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the water-insoluble sulfide to the soluble …
