Effect of Iron Ore Concentrate on Sintering Properties

iron ore concentrate contains a lower alumina. Recently it is more popular to be applied in commercial sinter plants to decrease the alumina content in sinter or combined with a high alumina low grade ore to reduce the production cost of sintering. However the productivity of sinter decreased with a decrease in the size of iron ore.

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines with other fine materials at high temperature, to create a product that can be used in a blast furnace. The 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 properties of the

The level of impurities and loss on ignition in iron ore has also been slowly increasing. Finally, the proportion of fine material in the available products has increased considerably for most iron ore fines. This has been found to have significant impacts on sinter quality and sintering performance. Magnetite concentrate is typically high in Fe grade and releases extra heat when oxidised to hematite. The

Iron Ore Concentrate - Iron Ore

Iron Ore Concentrate. Iron ore concentrate is an output product from processing ores which have been grinded to separate disadvantageous elements and produce a higher quality product with about 65 % iron in comparison with the fine and lump. It is sold to sinter and pellet producers and because of its quality, usually its price is a little more but is overall priced competitively with iron ore fines.

The Relationship Between Mining and Sintering

Sinter is the primary feed material for making iron in a blast furnace, and we have previously written about sintering and how it is a step between mining ore and steelmaking. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control
