Environment Canada works to address the environmental impacts of mining. Waste rock and mine tailings can result in releases to water and soil. Acidic drainage and the leaching of metals from the mine workings and mine wastes may occur at metal mines. Acidic drainage can cause significant impacts on water quality and aquatic ecosystems.
environmental and social impacts of mining in Ontario. For many communities, mining holds attrac-tive potential for economic benefits in the short-term. However, it is also important to understand what mining means in the long-term for northern ecosystems and community health and prosperity.

Smarter steels depend on high-quality raw materials. As one of the worlds 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.
Feb 24, 2007 Environmental impact assessment studies were carried out in the iron ore mining areas of the Goa region using both qualitative and quantitative methods.
