Cleaning up mining: a new industry group hopes to raise the profile of cleaner mining innovationsThe mining industry is often portrayed as a dirty industry, using old technologies and without regard for the environment. Yet increasingly, the mining industry is taking a proactive approach to improving environmental performance and using new technologies that decrease water and energy use, minimize environmental disturbances, and better remediate mine sites after mining operations are complete.
EPA casts doubt on Pebble MineThe U.S. Environmental Protection Agency (EPA) has issued a new report casting a large shadow over the prospects for the proposed Pebble mine in Alaska. The EPA study is not an evaluation of a specific mining proposal, but rather, assesses the potential impacts of mining in the Bristol Bay region by creating 3 mining scenarios.
Does mining use mercury?Mercury was once used throughout the world in gold processing. This process has since been replaced by more efficient and less environmentally damaging techniques.
What is the role of arsenic in the mining industry?Arsenic is a naturally occurring element commonly found as an impurity in metal ores, and is produced commercially for use in pesticides, wood preservatives, and metal alloys. Arsenic can be toxic in large doses, and the mining industry monitors and prevents its release into the environment.
What are the water quality concerns at mines?The
use of water in mining has the potential to affect the quality of surrounding
surface water and groundwater. In response to environmental concerns and
government regulations, the mining industry worldwide increasingly monitors water
discharged from mine sites, and has implemented a number of strategies to prevent
water pollution.
How are the effects of mining on water quality monitored?Because of water quality concerns, surface and groundwater at mine sites is monitored before, during, and after the operation of the mine. The information collected by water monitoring programs is used to assess the effects of the mine on the surrounding environment and develop appropriate water management plans.
