Iron ore - Wikipedia

Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined. There are four main types of iron-ore deposits worked,Effects of iron-ore mining and processing on metal,,15/08/2008· 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).Mines and environmental impact - SGU,Mining waste has different characteristics depending on the type of ore being mined. Our Swedish ores can be roughly divided into oxidic and sulphidic ores. The oxidic ores predominate in Norrbotten's iron ore field, while the sulphidic ores are more prominent in, e.g. the Skellefteå field in Västerbotten. However, Sweden's largest sulphide ore mine, Aitik, is in Norrbotten.

The iron ore tailings consist of a moderate amount of various heavy metals, e.g., copper, iron, manganese,Appendix 2: Environmental and Social Impacts of Mining,to fossil fuels, coal, and metal mining (Matthews et al., 2000:107). The amount of waste produced depends on the type of mineral extracted, as well as the size of the mine. Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, withEnvironmental Risks of Mining,Deforestation due to mining leads to the disintegration of biomes and contributes to the effects of erosion. In situ leach (ISL) mining ISL mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock (World Nuclear Association, 2012).
