  • Environmental impact of iron ore mining Wikipedia

    Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)·n(H2O)) or siderite (FeCO3). Roughly 98% of iron ore on the global market is used in iron and steel production. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iro

  • Iron is a stormwater pollutant and requires treatment

    Iron is white, silvery metal that oxidizes quickly when encountering water and oxygen. Dissolved iron as ferrous iron (Fe 2+), ferric iron (Fe 3+) and particulate iron, are forms commonly found in stormwater.Naturally present in groundwater, iron in these forms can make its way into the environment through stormwater in contact with groundwater and surface water.

  • Harmful Environmental Effects of Resource Extraction

    The direct effects of petroleum extraction on the environment are limited to land subsidence when the oil is at shallow depth or visual harm from the drilling rigs or pumping facilities. The indirect effects are much more devastating to the environment, from the effluent of processing facilities to accidents such as the Exxon Valdez or BP’s Deep Water Horizon and intentional spills caused by

  • Pollution From Mining TheWorldCounts

    The water pollution is caused by acid that drains from the “Iron Mountain” mine, known as acid drainage. Acid drainage is serious stuff. With a pH value of 0, the groundwater near the “Iron Mountain” has been found to be 10,000 times more acidic than battery acid (this is VERY acidic). It’s the highest concentration of acid in the world. In places, the acid is so concentrated it has
