2016-6-27 · As the prime material for steel, iron ore is critical for all sectors of our economy and the charac-teristics of the global iron ore market influence the business strategies of companies that are active in this market. In turn, business strategies determine the social and environmental impacts of iron ore (PDF) IMPACTS OF IRON ORE MINING ON WATER ,Wong, M. H. "Environmental impacts of iron ore tailings T he case of Tolo Harbour, Hong However, extraction of iron ore has numerous negative impacts on the environment.
The environmental impacts considered in the study were embodied energy and greenhouse gas (GHG) emissions, while the functional unit was 1 t of iron ore, ready for transport to downstream metal extraction and refining facilities. Inventory data for these processing stages were calculated by the authors.Environmental impacts of iron ore tailings—The case ,Disposal of iron ore tailings along the shore of Tolo Harbour, Hong Kong has altered the adjacent environment. Due to the ever-expanding population, the vast development of various industries, and the lack of sanitary control, the existing pollution problem of Tolo Harbour is serious. The iron ore tailings consist of a moderate amount of various heavy metals, e.g., copper, iron, manganese
The extraction of iron ore involves surface (open-pit) or underground mining tech- niques (please refer to Chapter 7 (Stace, 2015) on Iron Ore Extraction Techniques). TheEnvironmental Impact of Steel TheWorldCounts,Environmental impact of steel production Mining of iron ore. The main ingredient in the production of steel is iron ore mined from Earth. Over 2,000 million tons of iron ore is mined mined a year about 95 percent is used by the steel industry. Iron ore is the world’s third most produced commodity by volume after crude oil and coal and
Global trade in embodied iron ore has grown faster than its extraction, by a factor of 2.7 between 1990 and 2008 (Wiedmann et al. 2014). Trade of embodied bauxite has grown by a factor of 2.4. Weighting according to actual environmental impacts has not been tried yet and is difficult, because different materials have different impacts,Environment Management Iron Ore Company of ,Through revegetation, compensation plans, education, inspections and environmental assessments, IOC aims at preserving the natural resources in the boreal forest and marine environment it finds itself part of. Environmental management at IOC looks at the entire mining life cycle and works to reduce impacts on the land, air, water and people where we work.
