tailings. Iron ore tailings containing around 48 - 60% Fe are generated from the iron ore washing plants and are disposed into tailing ponds without any further utility. These tailings in the form of slimes are not suitable in iron and steel making due to the presence of higher amount of gangue constituents.
Iron ore slime is which has the particle size of below 150 m is being discarded as waste during the mining and processing stages iron ore and it will be stored at the tailing dam. It is estimated that 18% - 25% of tailing will be generated during the processing of iron ore. read more
