Chromite mining wastes have the potential to cause serious environmental contamination. This occurs in places around the world where these wastes are inadequately managed. Overburden is an important type of mine waste. Overburden includes the soil and rock that is removed to gain access to ore deposits at open cast mines.
Waste from extractive operations ( 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
For iron ore mines, the stripping ratio ranges around This means that for every tonne of iron ore produced, double the quantity of waste is generated. In 200304 itself, SAIL generated million tonnes of overburden and rejects from its 12 mines in the

CONE CRUSHER. A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones.
Typically, for every ton of ore that is mined, 5 tons of overburden must be displaced. Overburden is not subjected to any chemical processes, but must still be removed in order to access ores. Overburden is usually managed by piling it on the nearby surface of mining sites in an area that will not interfere with ongoing operations.

Sep 01, 2008#0183;#32;Removal of overburden to access the ore can pose major problems in storage and reclamation. The stripping ratio (wastetoore) 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.
In mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore is a number or ratio that express how much waste is mined per unit of ore. The units of a stripping ratio can vary between mine types. For example, in coal mining the stripping ratio is commonly referred to as volume/weight..

Overburden is an important type of mine waste. Overburden includes the soil and rock that is removed to gain access to ore deposits at open cast mines. It is usually piled on the surface at mine sites where it will not impede further expansion of the mining operation, because moving large volumes of material is expensive. Sukinda Valley

Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks

Sep 18, 2011#0183;#32;Taconite is a lowgrade iron ore. Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined. The iron content, magnetite, is only 20 30% compared to 50 60 % iron content in red ore. Red ore is also referred to as direct shipped ore because it can be shipped without processing.
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.
