sintering of very fine iron ore

1990 Fundamental study of pore formation in iron ore

112 Sintering process Sintering of iron ore is a process [5,6,8] in which air is drawn down through a bed of raw mixture of iron ore, limestone, coke and other minor additiv The iron ore may be natural ore, which usually has a particle size up to 10mm, or concentrate which is very fine with a.

The World Leader in Ironmaking Solutions

In the Finex process, fine iron ore is charged at the top of a cascade of fluidized-bed reactors where it is heated and reduced to direct-reduced iron (DRI) by means of a reduction gas - derived from the gasification of the coal - that flows in the counter-current direction to the ore.

Iron processing

Sintering Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heatBefore being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick.
