The outflow of acidic liquids and other pollutants from mines is often catalysed by acid-loving microorganisms; these are the acidophiles in acid mine drainage. Acidophiles are not just present in exotic environments such as Yellowstone National Park or deep-sea hydrothermal vents.
Mar 21, 2012· Say bacteria. People think infection. Or yogurts. But in Chile, bacteria are being used to get at something this country heavily depends on: copper. Chile is the world's biggest copper exporter ...
Oct 09, 2014· Production of humic substances through coal-solubilizing bacteria. ... Results suggest that these bacteria can be used to exploit the LRC resulting from coal mining activities and thus produce HS in order to improve the content of humified organic matter in soils.
Open pit mining is usually found where coal seams are thick. Open pit mines can reach depths of a hundred metres. Equipment used in surface mines include draglines, shovels, bulldozers, front-end loaders, bucket wheel excavators and trucks. In large mines, draglines remove the overburden while shovels are used to load the coal.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
The environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products.In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that contain ...

Role of microorganisms in reclamation of coal-mine spoils. By: R S Upadhyay 1 and Richa Raghuwanshi 2. Introduction. The fossil fuel coal is largely valued for its energy content. Since the 1880s it has been primarily and widely used for electric/power generation.
The primary difference between coal and charcoal is that the two fossil product can attribute their occurrence to different methods. Coal occurs after living materials like plants and animals collect in a swampy region decay and degrade by decomposition of microorganism resulting in solid products, which can produce heat.
Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
A biologist or microbiologist studies bacteria. Though the use of bacteria is wide spread. Bacteria can be used in a wide range of applications from mining, bio-remediation, to production of vaccines.
Treatment of Selenium-Containing Coal Mining Wastewaters 6 Today, there are two different types of active, fixed-film systems that have received significant field testing with selenium-containing coal mining wastewaters – the fixed-film downflow filter (also known as a „packed bed reactor‟ – PBR) and the fluidized bed reactor (FBR).

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.
Coal Mining Methods. Coal is extracted from earth using two methods : Surface mining and underground mining. Both of them use big cranes to lift coal from beneath the earth. Further transportation of coal to thermal power stations is done with trains, trucks, ships or even pipelines. Surface mining is somewhat easier than underground mining.
Some of the problems that accompany the mining and use of coal are well known. Acid mine drainage results when coal beds and surrounding strata containing medium to high amounts of sulfur, in the form of compounds known as sulfides, are disrupted by mining, thereby exposing the sulfides to air and water.
When contour mining becomes too expensive, additional coal can often be produced from the mine's highwall by the use of augers or highwall miners. Open pit mining is usually found where coal seams are thick and can reach depths of hundreds of feet.
The primary difference between coal and charcoal is that the two fossil product can attribute their occurrence to different methods. Coal occurs after living materials like plants and animals collect in a swampy region decay and degrade by decomposition of microorganism resulting in solid products, which can produce heat.
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining .
Oct 23, 2012· Now several companies are demonstrating a way to use microörganisms that eat coal and excrete methane—the main ingredient in natural gas—as a possible means of extracting fuel from coal ...
