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...
1131 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground necessitating the removal of layer upon layer of overburden and ore In many cases logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden The...
