Sinter plant

Sinter plants agglomerate iron ore fines dust with other fine materials at high temperature to create a product that can be used in a blast furnaceThe final product a sinter is a small irregular nodule of iron mixed with small amounts of other minerals The process called sintering causes the constituent materials to fuse to make a single porous mass with little change in the chemical...

Process for transforming fines of iron or manganese into

Ore fines whose particles are nearly all below 150 microns in size are converted into material suitable for use in forming sinter by the addition of agglomerants to these ore fines the subsequent pelletizing of the mixture into spheres with a maximum size range of 6 mm and the hardening of the spheres by curing them at temperatures below 300 176 C...

Iron processing

Lumps and fines Crushing As-mined iron ore contains lumps of varying size the biggest being more than 1 metre 40 inches across and the smallest about 1 millimetre 004 inch The blast furnace however requires lumps between 7 and 25 millimetres so the ore must be crushed to reduce the maximum particle size Crushed ore is divided into...
