While mining is beneficial to the economy, both in terms of its own economic impact and the value to other industries of its product, it almost always has adverse environmental impacts and eventually health impacts. Although more than hundred billion tonnes of iron ore has been produced from Keonjhar 62% of
MELBOURNE, Aug 26 (Reuters) - High levels of dust at two of BHP Group's (BHP.AX) iron ore mines in Western Australia are impairing the health of workers and nearby residents, a union said...
Iron-bearing dust is one of the main solid wastes in the metallurgical industry, and currently, it is mainly disposed of according to accumulation, which brings great environmental risks. Therefore, this paper proposes a method of preparing X-ray shielding materials by hot pressing using iron-bearing dust as the filler and polyimide …
The Complicated Role of Iron in Ocean Health and Climate Change Iron dust may have played a significant role in the last ice age, and it could be an important factor in mitigating future...
ARGONNE, ILL. (Sept. 6, 2012) — Using ultrafast X-rays, scientists for the first time have watched how quickly electrons hop their way through rust nanoparticles. This gives key insight to how iron oxide, one of the most abundant minerals in soil, behaves and alters the condition of soil and water around it. This also demonstrates the potential of …
To provide safe working environments to the workers in a steel plant as well as the residents neighboring the iron ore piles, it is necessary to put dust control measures including windshield, dust net, application of covers plant …
Potential Health Effects: Inhalation: Chronic inhalation of iron dust can lead to accumulation in the lungs and a characteristic stippled appearance on X-rays. This condition, called SIDEROSIS, is considered benign in that it does not interfere with Basic Assessment for the Amendment of the Air Quality ... More
The grunerite asbestos identified in the iron ore mine is a known human carcinogen and merits special attention, although its presence in the mine appears to be an anomaly. The best evidence for the pathogenicity of grunerite asbestos has come from epidemiological studies of workers in factories where predominantly this fiber type was …
Many factors influence the health effects of metalliferous mining dusts and understanding the exposure pathways is critical, as is …
Barrick 2003), the addition of PM as iron dust can impose a new form of stress to the vegetation. The impact of this pollutant can affect multiple levels of biological organi-zation. While isolated effects of pollutants on plants may indicate the integrity of a particular species, an integrated view of the effects on different species can help ...

Dust emissions at sites of loading, unloading and stockpiling of processed materials (e.g. coal, iron ore, phosphorites) can have significant impacts on the surrounding environment. The grain size fraction of the final products is often fine (50–100 µm) and therefore easily dispersed.
Table 3 and Figure 3 show the life cycle evaluation endpoint of the steelmaking system, which is obtained by classifying and weighing all intermediate damage types. It can be seen from Figure 3 that molten iron, scrap steel, and auxiliary materials have a greater impact on the environment. Among them, molten iron has a greater …

Laboratory experiments suggested that every ton of iron added to the ocean could remove 30,000 to 110,000 tons of carbon from the air. Early climate models hinted that intentional iron fertilization across the entire Southern Ocean could erase 1 to 2 billion tons of carbon emissions each year—10 to 25 percent of the world's annual total.
According to Lauderdale, the impacts of iron fertilization in a dynamic ocean ecosystem are much less straightforward than those Martin saw in his bottles. "Over the last 20 or 30 years, we've gotten a much better idea …
