Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and ...
The major potential environmental impacts associated with mining and associated mineral processing operations are related to erosion-prone landscapes, soil and water quality, and air quality. These potential impacts are recognized and addressed in current mining operations as well as in some former mining operations by reclaiming areas of ...
Impacts of Mining on Our Environment (with Remedial Measures) Mining of minerals, being an environmentally unfriendly activity, has attracted attention from the stand point of environmental impacts and their mitigation. Another fact about mining is that it is a site specific activity and is only an intermediate use of the land because mining is ...
Mar 01, 2010· Coal mining wastes have, therefore, to be properly managed to ensure the long-term sta- bility of disposal facilities and to prevent or minimize any water and soil pollution arising from acid or alka- line drainage and leaching of heavy metals. 2.5 Air pollution Air pollution from coal mines is mainly due to the fugitive emission of particulate ...
Dec 17, 2016· Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.

The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines.
Mining occupies a respectable position in an economy as it creates huge business opportunities thereby strengthening industrial base and increases foreign exchange reserve. During the recent years Iron Ore production touched 175 MT from 14.0 MT in 2000–01 because of increased indigenous demand and upsurge in overseas. The hubs of iron ore production in India are JODA-BARBIL-KOIRA area of ...
