  Iron ore slimes beneficiation using optimised ... - ScienceDirect

  202281 · Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process. Aiming towards the good quality (>60% Fe) ore and its non-renewable nature, the mineral rich ore is depleting, and the slimes are increasing at a rate of ∼11–13% for the hematite reserves in India, as reported by the ...

  Recovery of Iron Values from Iron Ore Slimes of Donimalai

  20151221 · During production of calibrated (sized) ore, more than 50 % of the generated fines and rejects (Slimes) cannot be directly utilised in iron making due to its unfavourable granulometry, low iron content, high alumina and silica content. Approximately 10–20 % of the process plant input is discarded as slimes into slime ponds/tailing dams. …

  Application of response surface methodology for modeling …

  201551 · Srivastava et al. [10] studied the beneficiation of iron ore slime of size below 110 μm using hydrocyclone and spiral concentrator. Most of the heavy minerals including iron ore are treated through gravity concentration process due to considerable difference in specific gravity of ore and gangue minerals.
