Waste rock is generally the primary source of selenium in coal mining operations. When exposed to water, various selenium species will leach or migrate from the rock and enter the environment. ... Treatment of SeleniumContaining Coal Mining Wastewaters 9 With time, a biofilm develops on the media surface. ...
Tailing pond water represents one of the greatest environmental liabilities for mining operations and the disposal of tailings is one of its greatest projected challenges. Ecosphere can help mine operators explore chemicalfree methods for the treatment and processing of tailing pond water.
It includes substances such as human waste, food scraps, oils, soaps and chemicals. In homes, this includes water from sinks, showers, bathtubs, toilets, washing machines and dishwashers. Businesses and industries also contribute their share of used water that must be cleaned.

Mar 31, 2015· Water Pollution from Coal includes negative health and environmental effects from the mining, processing, burning, and waste storage of coal, including acid mine drainage, thermal pollution from coal plants, acid rain, and contamination of groundwater, streams, rivers, and seas from heavy metals, mercury, and other toxins and pollutants found in coal ash, coal sludge, and coal waste.
Once mining ends in each pit, this waste rock will be placed back in the pit and covered with water so it cannot continue to create acid. Until then, we will collect and treat
"The company would have to treat the mining waste water before draining it into rivers or land anyway so this way they also did something good," Adrian Viljoen, formerly an engineer at Keyplan, now Aveng, which built the facility, told Bloomberg.

Although passive water treatment has been used successfully to treat municipal wastewater and urban runoff, its use in the mining industry is still under development, largely because of the challenge of treating highly acidic waters. [18]
Obviously, acidic mine waste (usually referred to as acid mine drainage or AMD) like the contaminated water from Parys Mountain and other sites is a problem. There are an estimated 280,000 abandoned mine sites like Parys Mountain in the UK alone.
Mussel shells to treat polluted mining water Monday, 29 April, 2013 University of Canterbury (UC) researchers are investigating an ecologically engineered treatment system to solve wastewater problems, such as acid mine drainage, on mining sites.
Selenium has emerged as a water treatment contaminant of concern in industries such as mining, oil refining, and power generation. In southeastern Idaho phosphate mines, selenium has been a major issue for two decades and is currently the subject of a largescale federally mandated cleanup effort.
Water treatment products firm Envirogen Technologies Inc. has launched a new smallfootprint fluidized bed reactor system designed to treat low flows of seleniumladen coal mining waters economically and efficiently. The new system will allow coal mine operators to treat flows that start at less ...
