Reuse of iron ore mineral wastes in civil engineering

01-09-2008· Removal of overburden to access the ore can pose major problems in storage and reclamation. The stripping ratio (waste-to-ore) for surface mining of metal ores generally ranges from 2:1 to 5:1, depending on local conditions. The iron ore is predominantly mined by opencast mining throughout the country.

Overburden Wikipedia

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. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore.

Mine Waste Transfer and Disposal Methods Mine Tailings

Overburden Waste rock, or overburden, refers to the often large mass of initial soil and rock that is removed in order to get to the valuable mineral deposits in mining operations. Typically, for every ton of ore that is mined, 5 tons of overburden must be displaced.

Mining waste Environment European Commission

Waste from extractive operations (i.e. waste from extraction and processing of mineral resources) is one of the largest waste streams in the EU. It involves materials that must be removed to gain access to the mineral resource, such as topsoil, overburden and waste rock, as well as tailings remaining after minerals have been largely extracted from the ore.

For example, in India, in the Sukinda mining area, around 7.6 metric tons of solid wastes have been generated in the form of rejected minerals, overburden material and waste rock, and subgrade ore that have caused environmental degradation, mainly creating lowering of the water table as well as deterioration of surface and groundwater quality (Mohanty and Patra, 2011; Tiwary et al., 2005).

Understanding Iron Ores and Mining of Iron Ore IspatGuru

Mining iron ore begins at ground level. Ore is identified by diamond drilling core samples on a grid several meters into the earth. iron ore rock comprises a substantial percent of iron and the rest is impurities such as alumina and silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
