sintering: a step between mining iron ore and steelmaking

Sinter is the primary feed material for making iron and steel in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace

what is iron ore sintering? (with pictures)

Feb 22, 2021 · Specifically, iron ore sintering requires the use of fine ore, produced by crushing high-grade iron ore into particles only a few millimeters in diameter. Depending on the specific machine and iron ore sintering process used, substances such as coke breeze and burnt limestone are used to ignite and heat the iron ore particles until the particles congeal

sintering of iron ore fines in steel plant. 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

iron processing - ores| britannica

Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore

iron ore to sintering to steelmaking-analyzing metals

Sinter is the primary feed material for making iron and steel in a blast furnace. We recently wrote about sintering in our sister blog, Advancing Mining . Read the article to learn more about how sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials

enhancement ofiron recovery from steelmaking slag fines

Jul 28, 2016 · Steelmaking slags are usually processed for iron recovery by dry magnetic separation. The recovered iron-rich products are recycled back into the ironmaking and steelmaking processes to replace high-cost steel scrap and iron ores. However, current slag processing is far away from optimum conditions, especially for slag fines with small particle sizes, resulting in generation of nonrecyclable

iron ore- an overview | sciencedirect topics

4 Iron Ore Consumption. Iron ore is used directly in the steelmaking process in the blast furnace in the form of lump, pellet, and fines (see Fig. 5 ). (Fines are converted to sinter feed in a sinter plant.) Iron ore pellets are also used in the production of DRI and HBI. Sign in to download full-size image

iron ore sintering- sciencedirect

Jan 01, 2015 · Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation.As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material
