was investigated. The results, as shown in Figure 4, show
that when the reducing gas flow rate is increased from
2.5 m3/h to 3.5 m3/h, the TFe content of the magnetic
product fluctuates between 63.19% and 64.61%, and the
TFe operating recovery rate increases from 88.92% to
92.86%. However, when the flow rate of the reducing gas
is increased from 3.5 m3/h to 4.0 m3/h, the TFe grade of
the concentrate decreases from 64.61% to 62.93%, and
the iron operational recovery rate decreases from 92.86%
to 92.02%. After extensive consideration, the appropriate
reducing gas flow rate is determined to be 3.5 m3/h, which
can achieve a TFe grade of 64.61% and a TFe recovery of
93.22%.
