· Moreover, openpit mining is generally preferred in mining operations due to its applicability in all operable areas of exposed rock, minimum production loss and high production rate, especially for ores such as limestone, granite and iron ore that are exposed at the surface.
· Strip mining is done only when the ore body is in close proximity to the surface. Openpit mining – Openpit mining is the method in which minerals or rocks are extracted from the Earth via an open pit or borrow. Mountaintop removal mining – Mountaintop removal mining (MTR) is done by mining coal seams underneath mountaintops.
Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. 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 openpit ...
