The major steps in the process of open pit mining for iron

Apr 15, 2021

Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth

    Open pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal

    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

    Jun 22, 2018 The mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economy and the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have

    Jan 01, 2015 Open pit mining of iron ore is fundamentally simple when compared to underground mining. While ore grades have to be maintained at high levels in order to satisfy the market, commercial advantage is gained by the application of high-capacity modern mining equipment, but volumes have to be high and costs so low to remain competitive

    In particular, surface mining is used to retrieve sand, gravel, stones, coal, iron and other metals. There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining

    In open-pit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. This method commonly involves a sequence of benches from the surface to the deposit. As the open pit goes deeper into the ground, all of the benches above are extended outward

    Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and

    Nov 01, 2018 Open pit mining is one of mankind's greatest achievements in the ongoing search for precious ores such as copper, silver, iron, and gold. It describes the process of systematically excavating land and digging out the rocks and minerals in search of metallic ores and removing them via borrow or open pit

    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
