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 min 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 manage overburden waste rock at iron ore mining Manage Overburden Mining Iron Ore Waste Iron Ore Sishen Mine Exxaro Iron ore is mined by means of extensive open pits extending approximately 12km overburden waste rock at iron ore mining Tailings also called mine dumps culm dumps slimes tails refuse leach residue or slickens are the materials left over after the process of

For every tonne of ore we mine there are around seven tonnes of overburden which are moved to an area called the Overburden Emplacement Facility OEF or waste rock pile Overburden includes topsoil clay and a variety of rocks each of which is stored in distinct parcels in order to reuse materials wherever possibleWaste Rock Definition 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

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 267 Pages Report Check for Discount on Mining Waste Management Market by Mining Method Surface and Underground Metals/Minerals Thermal Coal Cooking Coal Iron Ore Gold Copper Nickel Waste Type Overburden/Waste Rock Tailings and Mine Water and Region Global Forecast to report by MarketsandMarkets

is similar to open pit mining It is used to collect mineral deposits that are close to the surface in horizontal beds In strip mining the overburden is removed and then lots of small holes are drilled in the rock just over the ore Explosives are then placed in the holes to break up the rock so that it is easier to find the mineralmanage overburden waste rock at iron ore mining Manage Overburden Mining Iron Ore Waste overburden waste rock at iron ore mining Tailings also called mine dumps culm dumps slimes tails refuse leach residue or slickens are the materials left over after the process of

Waste rock can be processed to a desired gradation by crushing and sizing like any other source of aggregate The hardness of the waste rock is determined by the rock type For example iron ores are often found in hard igneous or metamorphic rock formations so waste rock from iron or taconite ore processing is usually hard and denseBureau of Mining Regulation and Reclamation WASTE ROCK OVERBURDEN AND ORE EVALUATION February 28 Waste rock overburden and ore shall be evaluated for its potential to release pollutants to the environment and for its acid generation/neutralization potential The material shall be managed
