Open Pit Mining - IntechOpen

Feb 17, 2021Open pit mining is defined as the method of extracting any near surface ore deposit using one or more horizontal benches to extract the ore while dumping overburden and tailings (waste) at a specified disposal site outside the final pit boundary. Open pit mining is used for the extraction of both metallic and nonmetallic ores.

As a result, the ore was very porous and unable to support the weight of overlying rock layers, which slumped into ore bodies. The removal of silica thus allowed an increase in the iron content from an initial 25 to 35% to about 55 to 60% in the ore bodies. Mining of these ores was initially carried out in open pit mines, as shown below.
