Iron Ore Sintering: Process
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.

The fine-sized copper ore was first mixed with metakaolin in a plastic case before agglomeration. After this first mixing, the ore–metakaolin mixture and alkali activator solution were mixed in a plastic case by rapidly hand spraying the latter over the former, and the resultant mixture was subsequently transferred to a polyethylene …
Utilization of Pellet Fines in the Iron Ore Sintering Process
The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering …

Influence of Sinter Parameters on CO Emission in Iron Ore Sintering Process
Iron ore sintering is an agglomeration process of iron ore fines, fluxes, fossil fuel (coke and coal), and some iron-bearing waste materials in the ironmaking and steelmaking industry . Sinter is one of the main raw materials used in a blast furnace (BF) accounting for more than 70% ferrous burden of BF in China [ 2 ].
Iron ore beneficiation: an overview
Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has …
