Environmental Impacts of Metal Ore Mining and Processing

The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment.

Environmental Risks of Mining

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. Environmental hazards are present during every step of the open-pit mining process.

Mineral Resources: Formation, Mining, Environmental Impact

Mining and processing ore can have considerable impact on the environment. Surface mines can create enormous pits (see Figure Open Pit Mine) in the ground as well as large piles of overburden and tailings that need to be reclaimed, i.e., restored to a useful landscape. Since 1977 surface mines in U.S. are required to be reclaimed, and commonly
