Bangalore Chinnappa G, Karra RC Experimental and statistical evaluations of strength properties of concrete with iron ore tailings as fine aggregate. J Hazardous Toxic Radioactive Waste 24:04019038.
Common physical properties of tailings are; grain size, density, , bulk density, specific gravity porosity while some of the mechanical properties are shear strength and permeability. Some chemical properties of mine tailings include pH, chemical composition etc.

10/11/2020· The addition of iron ore tailings enhances the compressive strength and impermeability of UHPC mortars due to the filling effect of IOT and the pozzolanic reaction of part of the finer IOT when the substitution rate is no more than 40%. The replacement ratio of 40% shows the best results, with low permeability and the maximum compressive strength.
Tailings are ground rock particles that are produced during ore benefi ciati on and disposed in slurry form. The iron ores many a times contain so little metal that almost 32 per cent of the ore extracted ends up as tailings. The fine tailings generated are usually disposed off in tailing ponds. By the end of
Iron ore tailings are the waste generated during the beneficiation of iron ore. The beneficiation process reduces the solid impurities physically bonded to the iron ore, hence, producing an ore of greater iron composition. The process of improving the percentage iron content of the ore leads to production of large
Both the coarse and fine iron tailings display a higher compressibility than the coarse and fine copper tailings. According to the values of C c, the coarse iron tailings are characterized as a moderate compressible soil, and the fine iron tailings are high compressible soil. However, for the copper tailings, the coarse and fine tailings are characterized as low and moderate

07/06/2021· According to GB/T 312882014 and YB/T 45612016 , there are three types of IOT: iron tailings powder, iron tailings super fine sand, iron tailings fine sand. However, in most previous researches, IOT mainly covers three categories: iron tailings rock, used as coarse aggregate, of particle size >4.75 mm, is produced by mechanical crushing low grade ore and
