mining technology: beneficiation of Low grade

Lot of low grade Iron ore fines are generated during preparation of lumps, calibrated ores and sinter-fines. In addition to these fines, 10-15% of ore mined is generated as slimes and are discarded as tailings. These fines and tailings are potential sources to produce pellet grade concentrate after suitable beneficiation. Another source of pellet feed concentrate is from low and off grade ores such BHQ BHJ. All these materials can be beneficiated
