Project Proposal Reduction Roasting Of Iron Ore

Utilization of lowgrade BHQ iron ore by reduction

The reduction roasting process is one of the potential alternatives to overcome such challenges. Herein, we have presented the feasibility study using reduction roasting process on one of the Indian low-grade BHQ iron ore for the preparation of magnetite concentrate-based pellet feed materials.

Dolochar as a reductant in the reduction roasting of iron

The present investigation examines the viability of dolochar, a sponge iron industry waste material, as a reductant in the reduction roasting of iron ore slimes, which are another waste generated by iron ore beneficiation plants. Under statistically determined optimum conditions, which include a temperature of 900 C, a reductant-to-feed mass ratio of 0.35, and a reduction time of 30-45 min ...

Thermal Decomposition Kinetics of Siderite Ore during

Mar 26, 2021 The results in Tables 1 and 2 indicate that the TFe of siderite ore was only 22.99, and the iron minerals mainly exist in the form of siderite. The contents of P and S were 0.04 and 0.45, respectively. The low content of MgO 1.90 and Mn 0.61 implied that only a small amount of Fe in the siderite lattice was substituted by Mg and Mn.
