Abstract

Restriction in production of ore and Closing down Iron ore mines, spurred the mines to look for alternative routes like processing of BHQ/BHJ waste rock or processing of iron ore slimy plant tails. The latter route was logically and scientifically attractive as pellet grade concentrates may be produced at low cost with a possibility of partial reclamation of tailing pond area and mitigating vexed tailing pond management problem. The fine particle of processing of slimy tails has been addressed either by flotation or wet high intensity high gradient separation. This paper furnishes a few case studies of fine particle processing of some iron ore slimy tails spread across Orissa assaying 27% to 57% Fe, with 32 to 80% -10 microns slime content. The results indicate that it is possible to produce pellet grade concentrates and / or Cement grade concentrates with appreciable wt.% yield for different types of slimy tails varying in granulometry, silica, alumina and hydrated – anhydrous iron oxide content. In some cases, the above process also paved way for nil waste process where in the alumina rich tails produced may be used in local building material and pottery industry.
