microwave heating The main purpose is to carry out carbothermal reduction (Fe _two Ti _three O _nine +CO→Fe _two O _three +TiO _two +CO _two ）And then magnetic separation is carried out to select Fe from the roasted and reduced ferrotitanium slag _two O _3， Just Titanium ore powder and titanium slag were obtained. The microwave heating tunnel kiln equipment for ilmenite reduction roasting uses microwave feed energy to reduce and roast ilmenite slag, which is a high-tech equipment for treating ilmenite with high efficiency, energy saving and environmental protection.
