Pollution from Mining

Mining operations release heavy metals that can be extracted by water. Depending on the mine and its location, Ni, V, Cr, Mn, Cu, Pb, Zn and As can be released into the hydrosphere. Mercury Mercury was widely used to in California gold mines to extract the precious metal from solid ore.

Study points to potential water pollution caused by iron ...

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
