3. Methodology. The purpose of this study is to develop a model for concentrating iron-bearing minerals, mainly magnetite and hematite, from Thanatia until a concentration in equivalent-iron content similar to the one published in the ERC for hematite (Fe 2 O 3) is reached.This indicates a starting concentration of 3.6% iron in …

The estimated iron losses through Iron Ore Slime ($50-60%Fe) is approximately 10-25% of total iron ore mined, which is $18 million tons (MT) per annum in India [9]. All non-hazardous industrial ...

ore and then a representative sample of approximately 400 kg was provided by riffle splitting. Comminution of the sample took place in a sequence of crushing processes including large and mini jaw crushers and roll crusher which 80% of the obtained product was found to be finer than 2380 micron. Figure 1 shows the

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore.
