Pollution From Iron Mining

Environmental impact of iron ore mining Wikipedia

The main sources of emissions during both the construction and operation phases include the products of combustion such as nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide and fugitive dust from the operation of equipment. The main sources of combustion-related emissions during both the construction and operation phases are related to diesel generators, fuel-oil boilers, and from on-site road traffic. Fugitive dust emissions can occur during land clearing, ground excavation, and from equipment t

Environmental Effects of Mining Iron Mountain USGS

Jul 26, 2018 Acid mine drainage (AMD) is metal-rich, acidic water that is the result of water from mining activities flowing over or through rocks containing pyrite, a sulfur bearing mineral. This water reacts with pyrite and air to form sulfuric acid and dissolved iron.

Pollution From Mining TheWorldCounts

Time left till end of pollution. Iron Mountain Mine is a mine near Redding in Northern California. The site was mined for iron, silver, gold, copper, zinc, and pyrite until 1963. The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium. It is one of the most toxic waste sites in the US.

Mining and Water Quality USGS

Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.
