Ecosystems are affected by the physical perturbations of mining operations as well as the chemical alterations in soil and water Mining activities vary but can include soil compaction and conversely removal of the topsoil These alterations disrupt nutrient dynamics by minimizing the availability of nitrogen and There are both positive and negative effects of recycling on the environment Recycling involves the processing of used material For instance recycling a ton of steel means saving approximately 2500 tons of iron ore a fast depleting natural resource on a global scale Abandoned dump sites can severely damage the surrounding environment

Mining

Smarter steels depend on high-quality raw materials As one of the world's leading producers of iron ore we supply nearly half of our own iron ore needs and provide the types of coal that are essential to steelmaking Our mining assets provide supply security and quality for our own operations and a source of high-value raw materials for our customers

In Cameroon a 570‐km railway will link the Mbalam iron ore mine with the Atlantic coast (Toledano 2012) whereas in Tanzania a proposed road to the goldfields by Lake Victoria could bisect the Serengeti National Park and disrupt one of the world's greatest surviving terrestrial wildlife migrations (Dobson et al 2010)

Liberia is endowed with an impressive stock of mineral reserves and has traditionally relied on mining namely iron ore gold and diamonds as a major source of income The recent growth in the mining sector has the potential to contribute significantly to employment income generation and infrastructure development However the development of these mineral resources has

9 Replenishing the environment A seemingly simple but rarely prioritized activity replenishing mine sites and mine environments is one of the key factors to not only earning the respect and cooperation of those living near the mine but will ultimately protect the mine's impact on the environment

That can either be produced from 10 000 kg of gold ore or 10 kg of mobile telephones Figure 2 Ore grade has decreased over time across most commodities in Australia Adapted from Mudd G M 2009 The Sustainability of Mining in Australia: Key Production Trends and Their Environmental Implications for the Future

August 21 2017 About 60% of Australian mines are close to Indigenous communities How has mining affected them? About 60 per cent of mining projects in Australia are found in close proximity to Indigenous communities — meaning our mining companies are perfectly placed to help those communities grow and prosper while being good corporate citizens

Lead and Mercury Emissions from Mining Global releases of lead from smelting and refining nonferrous metals (e g gold lead zinc copper) total over 28 000 metric tons/year 1 Global releases of mercury from smelting and refining nonferrous metals total 710 metric tons/year – the second largest source after power plants

Environmental Risks of Mining

There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA] 2005) However the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well

December 12 2018 — Deep in the heart of steel country on a balmy September morning Cleveland City Council members professors and non-profit leaders hopped out of their cars and Ubers and filed into a conference hall to find out why an Ohio transportation agency had taken the unusual step of using public money to pursue an experimental form of electric transportation:

Different types of mining have various impacts on land For example strip mining results in the clearing of trees plants and topsoil [2] One effect of this type of mining on the environment is the pervasive problem of soil erosion which in turn leads to the pollution of waterways Another destructive type of mining is underground coal mining

The Amazon rainforest in South America has large quantities of copper tin nickel bauxite manganese iron ore and gold making it attractive to mining companies all around the world But as the governments of the eight countries that cross the Amazon eagerly try to capitalise on this wealth concern is growing over the deforestation caused by amongst other things mining
