What Are the Advantages of Open-Pit Mining? Reference

Full Answer. Another advantage of open-pit mining is that it allows miners to get rid of low-quality materials quickly and easily. This is known in the industry as high selectivity, and it is one of the most important advantages of open-pit mining. Other methods, which have a lower selectivity, make it more difficult to filter out the low-quality materials.
