iron ore mining pollution

Sources of pollution: mining. 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 Iron ore mining was the main cause of the increased concentrations of As and Cd, which represent a cancer risk for humans. We have measured the concentrations of toxic elements (Cd, Pb, As, and Hg) in 29 samples from agricultural soils in an iron ore mining area in the northern piedmont of Mount Wutai in Shanxi Province, China.

erals such as iron ore require larger and different infras-tructure than do low-volume, high-value minerals such as diamonds and gold. The negative impacts of mining are both direct and indirect. Direct effects occur within the immediate con-fines of the mining enterprise (Duran et al. 2013). In-

With the potential for such impacts, effective mining laws and regulations must be enforced and strengthened. Metallic mining – including iron ore. The extraction of metallic minerals such as iron, zinc or copper has a long history in Wisconsin, but legal regulation of their environmental impact and safety are a relatively recent development.
