Evidence of the impacts of metal mining and the effectiveness of mining
Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to societies, but it may also Except for bauxite, iron and manganese, which are listed as ores (gross weight), metal production is reported as metal content (net weight). In order to construct a homogeneous measure of extracted crude ore that is used as an input from the natural environment to the economic system, we applied country- and commodity-specific Surge in global metal mining threatens vulnerable ecosystems

Not So “Green” Technology: The Complicated Legacy of Rare Earth Mining
If REE mining produces such substantial environmental impacts that it contributes to the climate problem more than it mitigates, then there is an issue of purpose. Finally, if the communities with REE mining are also the ones experiencing the benefits of green technology in abating climate change, then they may view the tradeoff as worth the The questionnaire consisted of both open and closed ended questions. Aspects covered in the questionnaires were socioeconomic characteristics of the respondents, effects of rutile, iron ore and diamond mining on vegetation and land, and types of restoration measures and their effectiveness in improving environmental Environmental Impacts: Local Perspectives of Selected Mining

Environmental Impacts of Mining The World Counts
The environmental impacts from mining include: Destruction of natural habitat. Oil, fuel and chemicals spills contaminating surrounding soil, rivers and groundwater resources. Air pollution from mining processing operations. Drainage and runoff from mining sites, including acid mine drainage. Acid mine drainage can go on for thousands of years.Similarly, the other iron ore mining countries undertake most of the “international responsibility” of environmental pollution while providing valuable and cheap primary resources to the rest of the world.

Environment protection expenditure by the mining industry. Total expenditure for environment protection by the mining industry increased by 6% from $368.9m in 1996- 97 to $390.6m in 2000 01. Metal ore mining accounted for most of this expenditure (58%), followed by coal mining (24%), and oil and gas extraction (8%).In some countries, mining is responsible for significant amounts of water use, as well as water waste. Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air The Potential Negative Effects Of Mining On The Environment
