The Major Steps In The Process Of Open Pit Mining For Iron

1.1.3.1 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

    Reading: Open-Pit Mining | Geology - Lumen Learning

    Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is

    The pros of an open pit mine is that these mines usually produce a vast amount of ore without the costly process of removing overburden — the ore is often in a large area and close to the surface. However, a major con of these type of mines is that they are both dangerous to work in, and permanently alter the surrounding ecosystem

Once the ore was located, mining tended to follow the ore, assuming whatever shape the ore-formation was in. For ore deposits in veins, that typically means diggings shafts and galleries (or trenches, if the deposit was

    An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and loaded onto dump trucks, which then transport the ore
