Microwaves Applied to Carbothermic Reduction of Iron Ore Pellets
Results of reducibility tests of reduction conducted on iron ore pellets with carbon are presented in this work. Work done is centered on reduction kinetics using carbon as reducing agent with conventional heat supply (heat transfer process) compared with reduction kinetics where heat is supplied by microwaves to the whole volume. Ore used in this work is called "Alzada" which has reducibility ...
متن کاملPhytoremediation: a novel approach for utilization of iron-ore wastes.
Large quantities of iron-ore tailings are being generated annually in the world from mining and processing of iron ores. It has been estimated that around 10-15% of the iron ore mined in India has remained unutilized and discarded as slimes during mining and subsequent processing. Soil contamination resulting from mining activities affects surrounding flora and fauna and presents a large clean-...
متن کاملMathematical Model For Energy Saving In Induration Of Iron Ore Pellets Containing Solid Fuel
Mathematical model for a pilot scale iron ore pellet induration furnace has been developed which considers the process of induration including the reactions of limestone, magnetite and coke. The differential equations of energy, mass and momentum are solved simultaneously. The profiles of temperature, pressure and concentration are obtained. Performing separate experiments on sub processes; dry...
متن کاملIron ore: energy, labor, and capital changes with technology.
Resource gathering is depending on leaner crude ores. Iron ore mining typifies this trend. To make lean taconite iron ores useful required a technologic breakthrough-pelletization. The shift to iron ore pellets has the advantage that they require less energy and labor per ton of molten iron than high-grade naturally concentrated ores. Increased reliance on pellets causes a geographic shift of s...
