Low chromite containing overburden is usually dumped as a waste material during mining of chromite ore. A large quantity of such waste is generated in TISCO chromite mines, India. Since this overburden material contains 20–46% iron, it can be a potential adsorbent for toxic metal ions present in wastewaters and industrial effluents. Chat Now

Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining Get More →
Details of the alternatives that have been considered during development of the mine proposals and the 2.2.2 The Iron Ore Deposits The Project will mine ore from two deposits, Ouéléba and Pic de Fon. The process starts with clearing of vegetation and removal of overburden from the mining area. The ore is then extracted by drilling
Other waste rock (gangue) excavated from the ore body, and any coarse wastes separated during processing are stored in waste piles or in the base of tailings dam embankments. (11,12) By far, the major fraction of mining waste such as waste rock are disposed of in heaps (or piles) at the source.

''overburden'' or ''waste rock'') that must be moved or excavated to allow access to the metallic ore deposit. For most mining projects, the quantity of overburden generated by mining is enormous. The ratio of the quantity of overburden to the quantity of mineral ore (called the ''strip ratio'') is usually greater than one, and can be much
strip mining meaning: a method of obtaining substances such as coal from the ground that involves removing the top layer of soil instead of digging deep holes underground. Learn more.

Jul 15, 2019 · Keeping in view the rising demand for iron and steel in India, fresh exploration of iron ore resources, and thereby generation of mining wastes is on the anvil. Iron ore overburden, which is generated during selective mining, is one of such lowgrade iron resources which cannot be directly subjected to iron making because of the low iron content.
