Iron Ore Company of Canada. IOC recognizes that the mining industry has a direct impact on the environment. We extract ore from the ground. We process it using energy and water. We generate waste, emissions, and greenhouse gases. Through the entire process, we recognize that we have a responsibility to minimize, and eliminate where possible,...
While there are many factors or parameters that influence the "cradletogate" environmental impacts of metal production processes, one of the most significant parameters is ore grade. As higher grade reserves of metallic ores are progressively depleted, mined ore grades will gradually decrease.
The main impact of mining and oil development on these ecosystems is the alteration of the water regime, especially lowering of the water table and depletion of groundwater. These impacts may result in increased salinization of the soil and erosion, which eventually lead to a .
