Chromium Mining and Extraction | Chromium Mining Processing - GREAT MINING

The podiform deposits are generally mined by surface mining technique while the underground mining is employed to stratiform deposits. Open pit mining: The layers covering the ore of the chromium are first removed to reach the ore. The process includes forming the open pit, by removing the overburden rocks and the surface materials.

The Environmental Impact of Mining (Different Mining Methods Compared ...

Underground mining, where miners tunnel beneath the Earth's surface to extract mineral deposits, is rarer than open-pit mining. In 2014, it made up about 5% of all American mining operations — and has less of an impact on the surface. However, this doesn't mean that underground mining doesn't have an effect on the environment.
