Utilisation of iron ore tailings as aggregates in concrete
Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete.

Iron ore tailings. A number of representative iron ore tailing samples were acquired from different locations of the dry tailing disposal areas (cf. Fig. 2).As illustrated in Fig. 3, the tailings were loosely dumped as piles; thus, their sampling did not necessitate any particular practice and merely involved filling bags with a hand shovel.The solid minerals and mining sector contributed a paltry 0.5% to the Gross Domestic Product (GDP) in 2018, with annual production averaging 40 million metric tons valued at about 34 billion naira(PDF) Solid Mineral Deposits and Mining in Nigeria: -A Sector in

Behaviour of Compacted Filtered Iron Ore Tailings–Portland Cement
Failures of tailings dams, primarily due to liquefaction, have occurred in Brazil in recent years. These events have prompted the Brazilian government to place restrictions on the construction of new dams, as iron ore tailings deposited behind upstream dams by spigotting have been shown to have low in situ densities and strengths and are Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore Skip to main content LinkedInCement Manufacturing Process LinkedIn

Additionally, the whole bag was used to ensure that the standard gradation remained unchanged during preparation. The IOT sand used in the test was from iron tailings in [17]. It was reported that iron ore is one of the most common metallic minerals in Nigeria and is found in various locations in the north-western, north-central, south-western, and south-easternList of Some Nigerian Iron Deposits and Locations
