Environmental Risks of Mining - Massachusetts Institute of ...

Carbon output. Mining, like most heavy industries, is dependent on fossil fuels, which generate the energy needed to operate a mine. To combat these carbon emissions, some countries have enacted regulations requiring emission credits, but many countries do not have codes dealing with carbon output ("Molycorp, inc.," 2010).

Carbon Mining - GOXI

Carbon mining is a more effective path to climate stability than emission reduction because carbon mining can remove the carbon from the air faster than we add it, providing a rapid path to prevent sea level rise, ocean acidification and loss of biodiversity.


1.1 PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the post-closure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. 1.1.1 Exploration
