Green Mining
Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).

Iron ore
How is iron ore mined? Iron ore undergoes a series of processes from pit to port before export. First, we explore the geology of the region to find the best iron ore prospects for our mining operations. Once the ideal site has been chosen, the ore is drilled and blasted. It is transported to the primary crusher for processing.

The same evolution can be observed for iron ore production; for example openpit mines provide 97% of US ore output. Fourfifths of the world's bauxite is also produced from openpit mining and it increasingly characterizes the extraction of uranium ore. This move to openpit mining has resulted in a considerable increase in the scale of ...
Environmental Risks of Mining
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.
