Sintering: A Step Between Mining Iron Ore and

Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. Sinter Plants, that produce iron ore sinter, are important units in an integrated steel plant. They face several operational challenges due to frequent changes in input raw materials, the inability to instrument key equipment in the plant, and the absence of real-time sinter quality measurement. To address these challenges, Virtual Sinter®, a Virtual Sinter®: Digital Twin for Integrated Sinter Plants

Comminution and classification technologies of iron ore

The three primary and secondary crushing stations each crush 5000 tons of ore an hour (t/h) into particles smaller than 150 mm. This material is then conveyed to a 250,000 t surge stockpile prior to being fed into the processing plant. When the ore is fed into the processing plant it first enters the scrubbers, before being sent to wet screening.Key emissions from sinter plants. Iron ore sintering is a material preparation process employed world-wide in the production of iron and steel. According to statistical data on pollution, sintering plants rank second in terms of toxic emissions, after the incineration of municipal solid waste (Menad et al., 2006; Remus et al., 2013).

Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site. Some works have both pelletizing and sintering plants at the smelter sites. 1.1.3.2.2.2. Green Pellets4.2.3.1.3.2 Sinter Making. The iron ore fines (− 10 mm) are agglomerated using Dwight Lloyed sintering machine. The iron ore fines and coke breeze fines mix with moisture is fed on the sinter bed which is ignited by a gas burner to initiate sintering process. The hot sintered ore is discharged at the end of the machine.Sintered Ore an overview ScienceDirect Topics

Sinter Plant Operations: Raw Materials SpringerLink

The raw materials for an integrated steelworks can be classified into four categories, which are iron ores, fluxes, fuels, and reverts. The characteristics of these raw materials strongly affect the metallurgical properties of iron ore sinter and sinter plant performance. An optimal ore blend design is therefore essential to produce low costPrior to dispatch of sinter to the blast furnace for hot metal production, the sinter product from the sinter cooler is screened to remove smaller/finer particles. The undersize so generated is called internal return fines, which are generally recirculated into the sintering machine. A very high level of internal return fines generation limits the use Prediction and Optimization of Internal Return Fines Generation in Iron

Biochars in Iron Ores Sintering Process: Effect on Sinter

The article presents results of the research on the use of chars produced during pyrolysis of residual biomass as a substitutional fuel in the iron ore sintering process. Such an approach allows to implement circular economy and industrial symbiosis to the iron and steel branches. The effect of the substitution of conventional coke breeze fuel used for recycling.

Iron Ore Processing, General SpringerLink

The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.Sintering is a crucial process in steel mills to prepare the feed for blast furnaces to make iron, whereby iron ore fines, flux, recycled products and coke breeze or anthracite are agglomerated toIron ore sintering.

Reductants in iron ore sintering: A critical review

Consumption of fuel plays a vital role in sinter making. Specific fuel consumption alters from plant to plant, and reductant use varies approximately from 45 to 60 kg/ ton of gross sinter. Similarly, the particular fuel consumption attributed to around 17–20 % of the total cost comes from the sintering process, as shown in Fig. 1.The process of sintering to improve the physical and chemical properties of iron ore for use in blast furnaces is well documented (Nakano et al. 2009; Senk et al. 2006; Aries et al. 2006; Xhrouet and De Pauw 2004).
