  • Mineralogical Characterisation of Iron Ore Tailings by

    The mineralogical characterisation of tailings of iron ore samples used an integrated mineral analyser known as TIMAMIRA The TIMAMIRA system was designed specifically for the mining industry and enables fast quantitative mineralogical analyzes of rocks, ores, concentrates, tailings, leach residues and foundry products The system consists of a software scan control and minerals data analysis,adverse impact of indiscriminate mining of natural sand, iron ore tailings which is the waste products of mining industries is used as an alternative to the river sand in the manufacturing of concrete The KIOCL company which was a leading company in India in the mining activities of iron ore has dumped about 200 million metric tons of iron ore tailings at Lakya Dam The company conducted mining for more than 25An Experimental Study on Utilization of Iron Ore Tailings

  • Filtered tailings in Western Australian iron ore projects

    Traditionally, tailings disposal from beneficiation type processes utilised in Iron Ore mining use slurry systems The tailings, mostly comprising silts and clays, are usually deposited in valley type tailings storages as the terrain adjacent to many iron ore mines lends itself to this type of tailings storage design These types of facilities have been successfully used since the 1980s However, one of the main disadvantages of these types of facilities is the requirement for large water resources as the tailingsThe cementstabilized iron ore tailings may be incorporated in road constructions as they easily fulfill strength requirements of base and subbase course layers, while the bentonitetreated tailings are applicable as cover materials in layered disposal of tailingsStabilization of iron ore tailings with cement and

  • Geotechnical Properties of Mine Tailings | Journal of

    In order to maintain the normal mining operations, several methods are proposed for tailing disposal, including disposal of dry or thickened tailings in impoundments or freestanding piles, backfilling underground mine workings, subaqueous disposal, and the most common method, the disposal of tailings slurry in impoundments that involves the transport of tailing mass in slurry pipes to an impoundmentThe main advantages of Filtered Tailings (FT) are related to water reduction in tailings disposal when compared with other methods, once it allows the geomaterial to be disposed close to optimum water content, thus allowing a better tailings compaction, and consequently increasing tailings shear strength for both drained and undrained conditions Another advantage is the significant amount of water recovery during oreGeotechnical Tailings Characterization from Cuiabá Mine
