In mining, overburden is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden

The excavated area is 200 metres long 20 metres wide and 2 metres deep with a listed swell percentage of 40% for the material. The bank excavation volume = 200 * 20 * 2 = 8000 m³ -> 8000 Bank cubic metres (BCM) Loose volume = 8000 * 1.4 = 11200 m3 -> 11200 Loose cubic metres(LCM) The same excavation in
Open pit and open cut mining are the least expensive techniques for the ore extraction. Overburden and stripping ratios are important in determining whether a deposit is to be mined. The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1

The primary and most prevalent waste generated by many mining operations is waste rock, or overburden. Waste rock, which consists of rock and target minerals in concentrations too low for economic recovery, is removed along with the ore. Waste rock includes granular, broken rock that ranges from fine sand to large boulders, depending on the ...

Iron mining operations began on the Mesabi Range in 1884 where strip mining was the most common method used to gain access to the ore. The open pits mines and spoils banks formed from the removal of overburden to gain access to the ore are still present today. As the rich ore was depleted taconite mining operations began.
A large volume of overburden and mine wastes is generated during the extraction and beneficiation of the low grade ores. The waste low grade manganiferous iron ore fine from southern part of India was studied for recovery of iron values. The chemical assay of the sample is 52.36% Fe, 4.75% Mn, 8.5% SiO2 and 2.82% Al2O3. The characterization study of the

Commissioned in late 2017, the two CDE processing plants wash, separate and gravity beneficiate about 17 Mt of low grade overburden iron ore that was stockpiled in waste dumps into a high-grade saleable product with a 63% iron content – upgraded from an average low-grade grade of between 45% and 50% iron content in the waste dumps, explains Warren.
In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body.
