conomic drivers in Southern Africa. However, due to mining and minerals processing activities, huge amounts of waste are generated that have potential negative impacts to the environment. Various wastes such as wastewater, particulate gases, overburden, waste rocks, tailings and slag are generated during the value addition of the ores. Although …
The mining waste involves materials that need to be discarded to get access to the mineral resources (such as topsoil, overburden and waste rocks), and materials remaining after selection/processing/treatment (operating residues, as well as tailings); indeed, the desired mineral may be present in the ore in minute amount (less than 1%).
This study aims to evaluate the effects of the utilization of iron ore overburden (IOO) materials compared to aggregates (VA) on the characteristics of hot mix asphalt (HMA) considering Topeka and binder layers. Mechanical performances, environmental impacts, electrical sensitivity, and deicing efficiency of laboratory HMA …
Sectors that dispose of tailings and waste rock may include, but are not limited to, coal, diamonds, potash, oil sands, metals (which include copper, nickel, lead, zinc, gold, silver, iron ore and uranium), quarries, industrial minerals …
Mathematical modeling was deployed to predict air quality during the construction and operation phases of an iron ore mine project in Maharashtra, India. A …

Open pit mining is defined as the method of extracting any near surface ore. deposit using one or more horizontal benches to extract the ore while dumping. overburden and tailings (waste) at a ...
Tailings, also called mine ... Tailings are distinct from overburden, which is the waste rock or ... or the slurry produced from tar sands mining.
Operations in surface iron ore mines involve removal of large quantities of overburden/waste and their emplacement as external dump and/or backfilling of the excavated area. Opencast mining operation results in the removal of overlying soil of iron ore deposit and formation of fragmented rock as overburden dumps (Ghosh 2002 ).
Planning and implementation of the disposal of mining wastes require careful consideration in order to establish ecologically acceptable disposal practises. Overburden and mine development rock are the two forms of waste rock produced by mining operations. Mine development Rock is a byproduct of mineral extraction in underground …
Materials generated as a result of open-pit mining include overburden, waste rock, and mine water. Other wastes may include small quantities of oil and grease spilled during extraction.
Ancient remnants of former iron-ore mining made of overburden (PMM) are not very highly contaminated by heavy metals (HM). Only two (iron and manganese) from nine HM significantly exceed the limits.
This study investigates experimentally the cement/bentonite stabilization of iron ore tailings from the Golgohar iron ore mine, which is the largest producer of raw (un-smelted) iron products in Iran. A comprehensive series of compaction and uniaxial compression tests was performed on mixtures of cement/bentonite and tailings.
Meghahatuburu Iron Ore Mines (MIOM), with an annual capacity of 6.5 million tonnes, is currently facing similar issues with its waste dump. Slope failure in the overburden dump threatens the mine as it can bring the mining activities to a standstill.
Waste rock or overburden refers to the often large mass of initial soil and rock that is removed to get to the valuable mineral deposits. Typically, for every ton of ore that is mined, 5 tons of overburden is displaced.
Monitoring and estimating solid mine waste produced during mining operations at a spatial–temporal scale plays a fundamental role in waste management and mitigation of environmental impacts. Iron ore mining and processing results in waste production that may cause environmental degradation, therefore, the need to estimate …

A study on suitability of iron ore overburden waste rock for partial replacement of coarse aggregates in concrete pavements
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.
The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this …
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 is the rock or soil layer that needs to be removed in order to access the ore being mined. Overburden is also referred to as spoil or waste. Overburdens are removed from surface mining and do not contain toxic components, unlike tailings, which is another type of underground mining waste. Interburden, a related term, refers to the ...
This Global Standard sets the minimum requirements for the management of waste rock and ore stockpiles to minimize adverse environmental and human health impacts, to …
Planning and implementation of the disposal of mining wastes require careful consideration in order to establish ecologically acceptable disposal practises. …
Book Mine Waste Utilization. Share. As large quantity of iron ore is being produced around the world, accordingly large quantity of overburden waste and tailings are produced …
Open pit mining is defined as the method of extracting any near surface ore deposit using one or more horizontal benches to extract the ore while dumping overburden and tailings (waste) at a specified disposal site outside the final pit boundary. Open pit mining is used for the extraction of both metallic and nonmetallic ores.
Over 90% of the mining activities in developed countries adopt open pit methods [5]. In large open pits, the orebody is usually found relatively close to the …
