Environmental Risks of Mining

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 ...

Causes, Effects and Solutions for Mining

For example, there are African gold mines in which gold is separated with the help of mercury. Workers often do this process by using their hands without any protection. This behavior usually leads to contamination of these people which eventually leads to death. This example shows how dependent certain people are on the mining industry.
