Table 1 shows the main chemical composition of the iron ore fines used in experiment. The iron grade of iron ore fine A is 66%, SiO 2 content is 2.01%, the iron grade of iron ore fine B is 61.5%, SiO 2 content is 3.6%. The bond grinding index of each iron ore fine was tested first. Then the iron ore fines grinded by ball mill.

Oxidised pellets have become an indispensable high-quality charge for blast furnaces. Nevertheless, high-quality pellet feeds are becoming scarcer and scarcer. To broaden the range of sources of pellet feeds and reduce the production cost of pellets, more steel mills are predicted to use coarse iron ore fines with a relatively low iron grade and …
Beneficiation of the bentonite ore. The results of beneficiation showed that applying a flowsheet based on attrition scrubbing of the crushed bentonite ore followed by classification with a hydrocyclone succeeded in removing much of the associated quartz and calcite as an underflow (about 15 wt.%) fraction. So, this underflow fraction was ...
