Iron Mining In the Lake Superior Basin Minntac Iron Mine in Minnesota Project Report 11-1 October 2011 the ore body and overburden have been adequately characterized, the next step is approximately 560 million tons of tailings and 350 million tons of waste rock during Phase I (approximately 35 years).

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.

For iron ore mines, the stripping ratio ranges around 2-2.5.15 This means that for every tonne of iron ore produced, double the quantity of waste is generated. In 2003-04 itself, SAIL generated 4.76 million tonnes of overburden and rejects from its 12 mines in the country.16

options and associated impacts of overburden disposal. 1.1.5 Ore extraction After a mining company has removed overburden, extraction of the mineral ore begins using specialized heavy equipment and machinery, such as loaders, haulers, and dump trucks, which transport the ore to processing facilities using haul roads.

Strip mining is ideally applied where the surface of the ground and the ore body itself ar e relatively horizontal and not too deep under the surfa ce, and a wide area is

30-06-2019· Underground mining is used for ores that are deep in Earth’s surface. For deep ore deposits, it can be too expensive to remove all of the rocks above the ore. These methods are more expensive than surface mining because tunnels are made in the rock so that miners and equipment can get to the ore.

16-06-2017· Tailings Disposal of Mining Metal Ores & Industrial Minerals. Mining and ore-processing methods are similar in the metal-ore and non-metal mineral industries, as are waste disposal techniques. The wastes of interest are waste rock, overburden and ore-processing wastes (or tailings).

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
