If mining is not regulated, it can release harmful substances into the air, water and soil. Companies work hard to reduce these harmful effects. Here are the kinds of mining that cause environmental damages.
Open pit mining
It is the most common type of mining. It causes damage to the environment as a large amount of ore must be removed to get the small amount of mineral that is available. It can expose rocks that have been unexposed for many years, and when these are crushed, they may release radioactive elements, metallic dust, etc. into the air.
This method of mining involves huge movements of waste rock and vegetation. It can release toxic compounds into the water and air. Water becomes a contaminant and so pollute the surrounding region. In underground mining, hydraulic pumps are used which can remove the important topsoil that contains seed banks. So, it is difficult for vegetation to grow.
With this method of mining, toxic heap leaching fluids are released into the environment. It can affect the health of the people and the surrounding ecosystem as well.
This involves extracting and evaporating the brine solutions to get rid of the harmful elements. In doing so, these elements are released into the air. The drilling operations and transportation of brine solutions can affect the ecosystems.
During mining, precautions must be taken so that no harm is caused to the environment. Today’s companies use various methods of controlling or eliminating the release of harmful substances into the air, water or land. We should protect our environment by all means.
