The tragic loss of life and significant environmental impacts associated with the failure of a tailings storage facility tsf at vales crrego do feijo iron ore mine in brazil has highlighted the devastation that can occur when critical mine infrastructure fails.
Vale has 19 iron ore mines and 10 industrial beneficiation plants in the qf region.These produce almost 200 million tons per year of iron ore, which represents approximately 70 of the total production in the region dnpm, 2012 vale s.A., 2012.Production is forecast to increase approximately 10 between 2013 and 2017, and 50 by 2030.
Test results reveal that the introduction of cementbentonite to iron ore tailings requires higher water content for optimum compaction and results in lower dry density.The addition of bentonite increases the unconfined compressive strength ucs very little, whereas there is a great strength enhancement for tailing-cement mixtures, particularly after a period of moist curing.
Iron ore tailing is a by-product generated during washing of iron ore its amounts to be around 18-20 million tones per year in india.Storage of this huge amount of iron ore tailing in massive ponds pose environmental hazards.This study considers two indian sources of iron ore tailings marked as a1 and a2 their structural evaluation utilizing x-ray diffraction xrd and field emission.
