Iron ore tailings IOT are mining waste obtained during the beneficiation process to concentrate iron ore . The discharge capacity of tailings in China increases every year accounting for more than 50% of the world& 39;s tailings discharge. The storage of IOT accounts for nearly one-third of all kinds of tailings.
Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context iron-ore mines act as important sources of major metals mainly Fe and Mn but also associated trace metals into the environment Ratha and Venkataraman 1995; Wong 1981; Zabowski et al. 2001 .
Open pit mining disturbs larger areas than underground mining and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced tremendous volumes of waste rock are removed from the pits and deposited in areas nearby.
The environmental consequences of mining Iron Mountain became apparent only a few years after the start of open mining in 1896. Fish kills in 1902 in the Sacramento River near the city of Redding were the first documented effects and shortly thereafter several private lawsuits and an injunction from the U.S. Forest Reserve precursor to the Forest Service were served against Mountain
The effects of Minnesota’s iron mining industry can be felt far and wide – on local regional national and even international levels. Existing Minnesota Iron Mining Operations Iron mining helped contribute more than $3 billion to the state’s economy in 2010 and helped support more than 11200 jobs in Minnesota alone.
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 Fe 3 O 4 hematite Fe 2 O 3 goethite FeO OH limonite FeO OH ·n H 2 O or siderite FeCO 3 .
Mining adversely affects the environment by inducing loss of biodiversity soil erosion and contamination of surface water groundwater and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
