Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. these processes also have an impact on the atmosphere from the emissions of carbon which have.
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. hardrock mining exposes rock that has lain unexposed for geological.
Mining, part 3 in his three-part series, dr buck emberg presents a balanced examination of both the need for mining and the environmental consequences of extracting minerals. he explains that mining has been a human activity since before the stone age and will remain so in the future. he contends that mining is here to stay, and we must learn to live with mines and mining companies must learn.
