The Sintering Process of Iron Ore Fines IspatGuru

Mar 09, 2013· Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product

Sinter plant Wikipedia

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 properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

A Novel Approach for Utilization of Ultra‐Fines Iron Ore

The current study presents a novel approach for the utilization of ultra‐fines iron ore (−0.2 mm) in sintering process through its conversion into mini‐pellets (4–9 mm). The mini‐pellets were composed of ultra‐fine iron ore and calcium hydrate while coke fines were used as a coating layer.

Iron ore pricing explained Metal Bulletin

For example, the daily, weekly and monthly indices are listed because of the varied liquidity displayed by different parts of the market. Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references.
