The effect of calcining time on the enrichment of pyrochlore ore was further studied, the calcining temperature was fixed at 900 ℃. As can be seen from Fig. 7, when the calcining time increased from 15 to 30 min, the ignition loss rate and the tailings discharging yield increased significantly from 10.3% to 16.9% and from 21.0% to 38.4% ...

It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.
