Iron ore tailing/slime 150 m is produced after scrubbing and wet screening of a low grade iron ore Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation The present study aims to recover iron values from discarded slime containing assay 56% Fe % SiO2 and % Al2O3
Iron ore tailing is a kind of hazardous solid waste produced by iron and steel industry In order to separate and recycle iron from the magnetic preconcentrate of an iron ore tailing an innovative technological route of fluidized magnetization roasting followed by low intensity magnetic separation was proposed in this paper The effects of roasting temperature
Iron ore tailing was used as a raw material for the production of ferric chloride The general characteristics of IOT are presented in Table 1 The IOT has a size distribution in the range of to 300 µm with a surface area of m 2 g −1 Elemental analysis showed a material with high content of silicon followed by iron and alumina

sand partially or completely in cement concrete by iron ore tailing which is a waste from the iron ore industry and which has disposal problem leading to environmental pollution is Table 1 Physical properties of iron tailing used Physical Property Value Particle shape Spherical Density kN/ m³ Specific gravity Colour
immediately before flotation In Brazil the generation of iron ore tailings coarse or fine tailing is estimated at 20 40% by the weight of the total iron ore 18 Generation iron ore tailings IOT and environmental problems Iron mining is of great importance for economic development however it generates a huge extension of
The world produced an estimated billion tonnes of iron ore during 2015 Footnote 1 US Geological Survey Mineral Commodity Summaries January 2016 The fact that generation of tailing is about 10 15% of ore [] indicates that more than billion tonnes of tailings are generated annually leading to increasing amount of are known for leaching
The relative density of the tailings was varied as Dr = 50% Iron Ore Mining and Iron ResearchGate the professional network for scientists Table 1 uploaded by Francis Atta Kuranchie
Iron ore tailings were also used in other concrete applications For example Das et al [13] studied the use of IOT to develop ceramic tiles and their study showed that tiles produced at a maximum of 40% of IOT were superior in terms of scratch hardness and strength compared to European standard specifications In a related research Yao et al [14] produced
