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 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

In recent years developments in sintering have made it possible for sinter plants to include up to about 30 iron ore concentrate in the Fe raw material mix Thus the sintering process seems likely to retain its dominant position in terms of agglomeration of iron ore fines for blast furnace feed
Depletion of high grade iron ore resources leads to increasing use of ore concentrates as raw materials for sinter One of the methods to effectively utilize such concentrates is Mosaic EmBedding Iron Ore Sintering MEBIOS which pre granulated green pellets are charged into sintering bed with the mixture of other raw materials
Effect of Iron Ore Concentrate on Sintering Properties In this study a number of commercial iron ore concentrates were tested in a sinter pot to find their sintering characteristics in conventional sintering The intensive mixer was used in an intensive mixing process5 and a separate granulation process to study the improvement of sintering with the iron ore blend containing the concentrate 2
rect reduction of iron ore for the manufacture of iron and steel is preferred because it does not require coke manufacturing and has fewer environmental impacts Wherever feasible pel letizing should be given preferences over sinter ing for the agglomeration of iron ore The following pollution prevention measures should be considered

15 06 2021 Iron ore fines are agglomerated to produce sinter which is an important feed material for blast furnaces worldwide A model of the iron ore sintering process has been developed with the objective of being represen tative of the sinter pot test the standard laboratory process in which the behaviour of specific sinter feed mixtures is evaluated
The sinter produced with the addition of 3 red mud shows the highest reducibility These results indicate the suitability of recycling RM in the Egyptian iron ore sintering process with an amount not higher than 3 wt of the total sinter mixture charge
23 03 2017 The basic characteristics of Australian iron ore concentrate Ore A and its effects on sinter properties during a high limonite sintering process were studied using micro sinter and sinter pot methods The results show that the Ore A exhibits good granulation properties strong liquid flow capability high bonding phase strength and crystal strength but poor assimilability
13 08 2010 Iron Ore Concentrate Iron Ore Iron ore is the raw material required to make Steel through melting There are some kinds of Iron Ore in the earth that one of the main forms of them is Hematite and also more costly to produce the concentrates which are used in steel smelting is sold to sinter and pellet producers and because of its
iron ore sinter feed specifications for theBINQ Mining Chapter 6 Iron Making dian Bureau of Mines Lumpy iron ore 30 10 mm and agglomerates like sinter pellets form the feed for the production of pig iron in blast furnace whereas steel scrap lumpy iron ore 18 6 mm or pellets are the feed for sponge iron
