Utilization of such waste and tailings in concrete as a building material is beneficial for mining industry as well as construction industry. This chapter presents a systematic research study carried out to investigate the potential use of iron ore waste rock (WR) and iron ore tailings (IOT) as coarse and fine aggregates in concrete.

2.1. Waste rock (Mine Rock Piles) The solid material generated in the largest quantities by iron ore extraction is the material that overlies the ore body (the overburden) and the other rock that has to be removed to gain access to the ore (the mine development rock and waste rock). The quantity and composition of waste rock

The ore will be extracted through open-pit mining and transported from the mine to the plant by a long-distance conveyor belt. The plant, iron ore stockyards and distribution yards, piles of waste rock and overburden (containing iron ore with high phosphorus levels), and train manoeuvre and loading area are all sited in an

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 analysis, we provide a comprehensive examination of RMRs for 25 commodities for 2018. The results …

Fig 1 Steps in open pit mining of iron ore. Environmental issues. 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. Mine water usually contain dissolved or suspended constituents similar to those found in the ...

Background. If your facility meets the reporting criteria, you are required to report the disposal of tailings and waste rock to the NPRI. 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 and other applicable ...

The percentage of waste rock to ore excavated is defined as the stripping ratio ...

The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock. The ratio of waste rock/ore is called stripping ratio. For example, …

Open-cast mining of coal generates waste material, including rock and soil with different minerals, and traditionally dumped as waste over the valuable lands worldwide. Overburden (OB) is devoid of actual soil characteristics, low micro and macronutrient content, and a sufficient amount of rare earth elements, silicate, sulphate, and clay minerals.

Ultimately, some 3.3 billion tonnes of waste rock will be mined and located into overburden storage areas (OSAs) in and around the final pit. The OSAs contain unoxidised waste rocks, …

The ore-to-overburden ratio for surface mining is generally around 1:5 to 1:2 depending on local situations (Feng et al., 2021, Yellishetty et al., 2008).In 2008 and 2009, about 75 % of overburden materials and 25 % of tailings were generated as solid residues in Minas Gerais, Brazil (Schatzmayr Welp Sá et al., 2022).However, to the best of the authors' …

such as spent ore from heap leach operations, tailings, and waste rock units, including overburden material. Sub-surface mining often progresses below the water table, so water must be constantly ...

However, the specific gravity or unit weight of waste rock from the mining of iron ore and taconite will be considerably higher than that of conventional aggregates. The specific gravity of waste rock can be expected to range from 2.4 to 3.0 for most rock types and from 3.2 to 3.6 for waste rock from iron ore and taconite minings. Mill Tailings

Solid Mine Waste Overburden or Waste Rock: This term pertains to the extensive volume of initial soil and rock that must be excavated to access mineral deposits. Typically, approximately five tons of overburden need to be …

For this experiment, we used waste rock collected from the Schefferville iron ore mine (for more detail see Jean et al. 2020a). Prior to the experiment, we sterilized half of the waste rock with ...

Abstract Coal is the cheapest and thus the preferred energy source in developing countries. A huge volume of coal mine waste rock, which is known as overburden (OB), is generated due to the surface mining of coal. Due to convenience and the restricted ... Practical Applications The question of how to replace traditional construction materials with efficient …

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.

Waste generated from themining industry can be classif ied as overburden, waste rock, tailings, slags, mine water, water treatment sludge and gaseous waste. The various waste per mineral are indicated in Table 2 with an ... Das, S. K., Kumar, S., Ramachandrarao, P., Exploitation of iron ore tailing for the development of ceramic tiles, Waste ...

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. ... Three different iron oxide-based sorption media samples were tested for removal of phosphorus (P ...

Spent ore piles 1, surge piles, waste rock/overburden piles Seeps/French drains 1 Tailings impoundment/pile Heap leach runoff/seepage Pregnant, barren, overflow, and polishing ponds Product storage areas (e.g., concentrate pile) NOTE: On-site haul roads not constructed of waste rock or spent ore

Planning and implementation of the disposal of mining wastes require careful consideration in order to establish ecologically acceptable disposal practises. Overburden and …

To assess the suitability of iron ore overburden waste rock (OB-WR) as replacement of coarse aggregates in concrete, laboratory scale investigations were carried out. In the first stage,...

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.

Treating overburden like it is tailings is a waste of money, while doing the opposite can result in environmental damage and high remediation costs. Keeping the materials coming out of a mine separated can reduce …
