1 Production of Pig Iron by Smelting of Blended PreReduced Titaniferous Magnetite Ore and Hematite Ore Using Lean Grade Coal. Authors: Bitan Kumar Sarkar, Akashdeep Agarwal, Rajib Dey, Gopes Chandra Das. Abstract: The rapid depletion of highgrade iron ore (Fe 2 O 3) has gained attention on the use of other sources of iron ore. Titaniferous magnetite ore (TMO) is a special type of magnetite ...

Electric Arc Furnace Operation
· Titaniferous Magnetite Ore, Iron Mountain, Wyo. Four reductants and three slag conditioners were used in a series of tests to evaluate optimum melting parameters for use with a titaniferous magnetite ore from Iron Mountain, Wyo. As noted from the data given in table 13, a considerable excess of stoichiometric carbon requirement was necessary for sufficient reduction. .

Titaniferous magnetite ore is partially reduced with coal in rotary kilns and then melted in a furnace. ... which is dissolved in the molten iron. Since this oxidationreduction reaction is exothermic, the heat supply need only develop the kindling temperature of 950° C (1,750° F). After kindling, the electrodes are withdrawn until the reaction is completed; they are then reinserted into the ...

· Reduction behaviour of cold bonded selfreducing titaniferous magnetite ore (TMO) and lean grade coal briquettes have been investigated under isothermal condition. The reduction experiments of TMOcoal composite briquettes have been performed at varying temperatures ranging between 1273 and 1473 K for 3–60 min. The metallised briquettes are characterised by XRD and .

Salt Roast
· The typical titanomagnetite smelting operation entails (very simplistically) feeding the titanomagnetite with coal into a prereduction kiln. The prereduced material is then conveyed to a furnace where it is smelted to produce a vanadiumbearing pig iron metal and a byproduct titania (TiO2)rich slag. The vanadiumbearing pig iron is tapped into a shaking ladle where it undergoes oxidisation ...

prereduction of titaniferous magnetite. Prereduction is performed at a temperature of some 1100°C in a rotary kiln, in the Highveld Steel process. Laboratory isothermal reduction measurements were performed with orecoal mixtures at this temperature, to test the effect of ore particle size. The results show that size does limit the degree of reduction for particles larger than 15 mm ...
