  Existing and New Processes for Beneficiation of Indian Iron …

  202028 · This is mainly due to the reason that most hematite iron ores of India are very soft, generating around 35–40% of fines and slime during the process of mining, beneficiation and preparation of sized ore. The tailings and slimes generated from the hematite ores are 10–30% of the run of the mines and are discarded as waste [ 4 ].
