The role of micro-organisms in the formation of acid mine ...

The paper deals with the nature of mine drainage in the North Eastern Coalfield, Margarita, Assam (India). The drainages from the Margerita group of mines are found to be acidic with high sulphate ranging up to 1500 ppm and iron content rising up to 40 ppm. The total sulphur in coals is up to 7% out of which 50–80% is non-reactive organically found sulphur. The acidity mainly

2019-10-1 · These natural capacities can be exploited for the bioremediation of mine impacted sites. Microorganisms also play a key role in phytostabilisation, either indirectly by promoting plant growth or directly through metals and metalloids mobilization or immobilization in soils. Thus, microorganisms are important actors of mining sites remediation.

The role of microorganisms in gold processing and

2014-2-1 · Microorganisms can mediate gold solubilisation by oxidising the sulphide matrix of refractory gold ores making the gold more accessible to leaching by chemical lixiviants. Microorganisms can also excrete ligands which are capable of stabilising gold by forming gold-rich complexes and/or colloids (Reith et al., 2007a).

2020-10-1 · Abstract— The composition of the microbiome of acid drainage water of a quarry used for the mining of brown coal was studied. The water had a pH of 5.15 and contained 1.4 g/L of sulfate. Unlike acid mine drainage associated with mining of sulfide ores, the content of iron and heavy metals was low. Molecular analysis of the microbial community was performed by

Biomining: metal recovery from ores with microorganisms

Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.
