Addition of iron oxides to arsenic contaminated soils has been proposed as an effective remediation technique. The aim of the present work was to re-use iron ore broken pellets, i.e. a waste from mining industry, to immobilize arsenic within soil.
The facility manufactures a variety of products, primarily nonwoven fabric. In the early 1970's, waste solvents were disposed of in drums in a waste pit, which were later discovered to have leaked into the groundwater. The waste pit drums and surrounding affected soils were excavated in 1985. A total of 29 monitoring wells were installed at the ...

Kumar M Rupas et al., (2015) studied soil stabilization using Iron Powder. In this study deals with the stabilization of Black Cotton Soil using waste Iron Powder. Results showed that Maximum Dry Density and CBR values were improved after the addition of Waste Iron …
The binder additive 5% cement and 20% fly ash and 10% cement and 40% fly ash with mine tailings produced the highest compressive strength at 28 days, as shown in Fig -4. The experimental results of the present study indicate that a cement-fly ash composite binder can be very effective in stabilizing iron ore mine tailings.
beneficiation therefore, is to improve the iron content and decrease the alumina-iron ratio. Beneficiation and utilization of these fines would thus not only help in reducing the waste dump volumes for disposal as an environmental measure but also lead to conservation of mineral wealth by recovering additional values of iron.
High calcium in the municipal solid waste incineration (MSWI) fly ash made it a potential material for replacing part of the calcium flux used in iron ore sintering process. The results show that the sintering indexes were not negative affected but improved slightly as MSWI fly ash added, which is mainly because the ultra-fine material helped to obtain a better granulation and produced liquid ...

12%The iron-ore sintering gas cleaning residue was identified as hazardous waste, and Pb and Se exceeded the standard. The residue solidified by 20 % cement or 1 % chelating agent could be disposed in HW landfills; however, a continuing study of long-term stability of chelating product is necessary.
Novel biotechnologies are required to remediate iron ore mines and address the increasing number of tailings (mine waste) dam collapses worldwide. In this study, we aimed to accelerate iron reduction and oxidation to stabilize an artificial slope. An open-air bioreactor was inoculated with a mixed c …

the world for iron-ore reserves. Therefore, India is an important iron-ore producer and exporter. However, approximately 10–15% of the iron ore mined in India is unutilized, even now, and is discarded as tailings. The tailing wastes that are called ultrafines or slimes, mainly those ore solids having a diameter of less than 150 μm,
Of the iron ore exported 38.5% of the volume was iron ore pellets with a value of $2.3 billion and 61.5% was iron ore concentrates with a value of $2.3 billion. Forty-six per cent of Canada's iron ore comes from the Iron Ore Company of Canada mine, in Labrador City, Newfoundland, with secondary sources including, the Mary River Mine, Nunavut.

The waste, subgrade ROM and fine dumps of iron ore mines are characterized by high rock fragment contents, low moisture retention capacity, higher bulk density, low nutrients, lower pH and elevated metal concentrations. Use of suitable revegetation programme, that require the selection of right type of plants to be used vis-à-vis the site condition and characteristics, can enhance the long ...

Iron in rural groundwater supplies is a common problem: its concentration level ranges from 0 to 50 mg/l, while WHO recommended level is < 0.3 mg/l. The iron occurs naturally in the aquifer but levels in groundwater can be increased by dissolution of ferrous borehole and handpump components.
treatment of hazardous materials. Stabilization refers to rendering a waste less toxic through fixation of the contaminants that contain and/or by providing a stable chemical environment. Solidification is related to those operations which improve the physical and handling characteristics of the waste (Conner, 1990).

Lamani S R et al. investigated the utility of iron ore waste (IOW) in preparing non-fired bricks by using cement and fly ash. Bricks were prepared with different proportions of cement, fly ash, and IOW. The manufactured bricks were cured for 7, 14, 21, and 28d. Compressive strength and water absorption of bricks were evaluated.

Answer: The type, amount, and properties of mine waste produced at different mines vary depending on the resource being mined, process technology used, and geology at the mine site. While many mine wastes are benign, mining companies manage their waste in order to deal with the large volumes of w...
therefore stabilizing waste material on artificial slopes is essential for remediation efforts. Prior to mining, the iron-rich duricrusts are typically stripped and stockpiled to access the high-grade iron ore below. Canga, primarily composed of goethite and hematite, contains a high aluminum and phosphorus content, typically making it a waste
