1, the nature of iron ore to iron black microstrip shades of green dense block, interposed between the spots scarlet, semi-metallic ores gloss, hit the frangible brittle to be ground to a powder. The main minerals are magnetite, hematite, pyrite, calcite , chlorite. TFe accounts for 35%, (the magnet Fe3O4 accounts for 90%, hematite Fe2O3 accounts for 6%, other iron minerals accounts for 4%) S accounts for 2.31%, P accounts for 0.077%, SiO2 accounts for 30.67%, and Al2O3 accounts for 3.64%, CaO +MgO accounts for 2.85%. 3, process parameters, indicators (1) grinding fineness -200 accounted for 70%; (2) magnetic field strength H = 70KA / m (3) index iron ore grade TFe35%; iron concentrate grade 66.48%; iron recovery rate 91.37 %; iron concentrate contains S below 0.2%. 4.
