mining technology: beneficiation of IRON ORE

Magnetic separation and flotation are the most widely accepted technologies for the upgrading of iron ore particles, but these processes result in iron concentrate with high amounts of very fine and/or interlocked silica particles (Yang, et al 2003). Mohanty (2002) also found that the ability of flotation to treat mixed-phase (middling) and weakly hydrophobic particles is not satisfactory. To address the aforementioned problems and thus to achieve a higher iron ore

Kiruna Iron Ore Mine, Sweden Mining Technology

Since mining began at the iron ore operation more than 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) produced over 950Mt of ore, yet only one-third of the original ore body has been extracted. Since mid-1999, Kiruna’s haulage level at a depth of 775m has been replaced by the next level down at 1,045m and expansion is being carried out to increase the depth further, which will support production until 2030.
