Opencast mining involves drilling and blasting to remove topsoil and overburden. The mineral-bearing ground is cut in the form of bench systems to excavate the ore. The extracted ore is hauled to the surface and subsequently transported using trucks or dumpers to the crusher, where the ore is converted into smaller pieces.

How does ground-level ozone form? Tropospheric, or ground level ozone, is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC). This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources ...

Acid rain occurs when pollutants, such as sulfur dioxide and nitrogen oxide, mix with rainwater and fall to the ground. Acid rain can dissolve essential nutrients in the soil, making them less available to plants, and change the soil's pH, making it more acidic, affecting plant growth. 6: Mining Activities
