There is growing public concern about the condition of fresh water in Canada. Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments.
Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

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 and aquatic ecosystems. Chemicals that are used to ...
However, there is a serious concern of air pollution due to iron ore mining activities. In order to assess the impact of mining activities on the environmental regime, the air quality depreciation index was adopted for this study due to its realistic and meaningful presentation of deterioration in ambient air quality. The index had been applied to the ambient air quality monitoring results of ...

SOURCES OF POLLUTION IN LEAD ZINC CONCENTRATE ... technological process of lead zinc ore flotation in the Flotation Plant "Kopaonik" Leposavić can be divided into three groups: water pollution, soil pollution and air pollution.
Acid mine drainage is the primary source of water pollution from mining. Mining unearths large amounts of ore that contains precious metals, such as gold and silver, as well as iron and other sulfides. When sulfides in the ore are exposed to water and air, sulfuric acid is created, which can seep from mines and waste rock piles into streams, rivers, and groundwater. This seepage is called acid ...
