Iron Range's coppernickel mining poses opportunity and possible

Mar 26, 2013 That's why Miller calls sulfur the blessing and the curse in coppernickel mining. Without it, the metals wouldn't be congregated closely enough together to make mining them economically feasible. But because of that sulfur, mining companies have to manage the acid mine runoff, which he said they 

Runoff Water Management in Bailadila Range, Kirandul, India

Dec 1, 2015 Iron is generally mined by open cast or strip mining, rather than tunneling the earth. This method includes extracting minerals from an open pit. Mining operations on Bailadila hill has caused tremendous pollution in the water of river Sankhini and other rivers and streams. As a consequence of runoff from 

From Coal to Canvas: An Artist Turns Toxic Runoff into Palette

May 13, 2014 That goal is made easier by his collegiate surroundings. Partnering with Ohio University engineer Dr. Guy Riefler, they developed an entirely new type of paint made of the runoff from Ohio's old coal mines. "This is an area where we have massive coal mines left abandoned," says Sabraw. Iron ore and other 

How is water managed and treated in mining Mining Facts Org

Intercepting and diverting surface water (rain and snowmelt runoff, streams, and creeks) from entering the mine site by building upstream dams to reduce the potential treatment, ways to recycle the sludge are being explored, such as the production of marketable iron concentrate from acid rock drainage from coal mines.

Assessment of Environmental Impact of Iron Ore Mining and its

Jan 16, 2017 As the mining method for Iron is usually open cast, it degrades natural landscapes, surface and ground water, flora and fauna, as well as the ambient air quality within the mining area and its environs. Water quality is contaminated due to surface runoff and leachate that are generated from large volume 

Rio Tinto's Ore Mining: Making Hay from Water by Peter Marcel

May 30, 2017 When the Rio Tinto mining company decided to increase its output of iron ore by 25% in its Marandoo loion, it had to deal with an unexpected problem: an exce.

Acid mine drainage Wikipedia

Metal mines may generate highly acidic discharges where the ore is a sulfide mineral or is associated with pyrite. In these cases the predominant metal ion may not be iron but rather zinc, copper, or nickel. The most commonly mined ore of copper, chalcopyrite, is itself a copperironsulfide and occurs with a range of other 

Assessment of surface runoff from iron and steel mills epa nepis

A field survey was designed to deter mine the quantity and quality of stormwater runoff from iron and steel mills with sampling concentrated on the following activities or operations which were rated as having the greatest potential for contaminating stormwater: • Coal storage piles • Coke storage piles • Slag Dumps • Iron

Minnesota's Environment Mining Truth

This is not our grandparents' iron mining — sulfide mining has never been done in Minnesota. While iron mines have significant environmental challenges of their own, the sulfuric acid that is produced with sulfide mining makes it particularly difficult to avoid polluting nearby lakes, streams and ground water.

Iron is a stormwater pollutant and requires treatment StormwateRx

Iron is transported into the environment through water typically. It is naturally present in groundwater. However, drainage from abandoned mines can deliver toxic levels of iron into rivers and streams.

What are the water quality concerns at mines? Mining Facts Org

In response to environmental concerns and government regulations, the mining industry worldwide increasingly monitors water discharged from mine sites, and has Ironrich mine waters have been used in water treatment plants to remove other contaminates, and mineralized mine waters are occasionally used in spas .

Improved Water Consumption at the Sishen TSF Complex Iron Ore

The Sishen Iron Ore Mine is loed approximately 50km southwest of Kuruman in the Northern Cape Province, in South Africa. Any runoff water from an extreme rainfall event (1:50year 24hour rainfall) will be contained on top of the tailings dams and decanted in the shortest period possible. Weather Data: The mean

Sources and fates of heavy metals in a miningimpacted stream

Aug 15, 2014 Heavy metal contamination of surface waters at mining sites often involves complex interactions of multiple sources and varying biogeochemical conditions. We compared surface and subsurface metal loading from mine waste pile runoff and mine drainage discharge and characterized the influence of iron

Metallic Sulfide Mining

But not all mining has the same impact. The Upper Peninsula¶s familiar iron mines extract the metal from oxide ores as opposed to sulfide ores. When sulfides come into contact with air and water, sulfuric acid is generated. The acidic run off mobilizes heavy metals like lead, cadmium, aluminum, selenium, and arsenic.

NOAA's National Ocean Service Eduion: Nonpoint Source Pollution

Active mining operations are considered point sources of pollution. But drainage or runoff from abandoned mining operations often adds to nonpoint source pollution.
