Nov 10 2020 In this process most iron and some vanadium are reduced to hot metal and further treated to recover iron and vanadium whereas Ti is almost entirely not reduced and concentrated into the blast furnace slag.23 Generally the normal iron ore sinter is composed of iron-bearing minerals 4070 vol. hematite Fe 2 O 3 and magnetite Fe 3 O 4 .
Jan 01, 2012· While the bentonite addition decreased, ... 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.
For example, the addition of 1% bentonite, containing 85% SiO2+Al2O3, decreases the iron content of pellets by 0.6-0,7% by wt (de Souza et al.,1984, Kater and Steeghs, 1984).Any increase in silica content can lead to appreciable cost increases of the steel production (Chizhikova et al., 2003, Schmitt, 2005).
for fine iron ore, namely: sintering, nodulizing, briquetting, and pelletizing. Sintering is where the fuel and ore are combined and ignited to form porous agglom-erates. Sinter is a popular feed for blast furnace operations; however, the drawback is that the concentrate in this form can be used only in very limited quantities at the sinter plants.
The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes and fuel. Sinter fines returning from the product screen, always form part of the feed material in all sinter plants. The ore and additives are fed into the revolving drum for homogenous mixing with addition of the water.

As a result, sintering plants are normally located in close vicinity to the blast furnace, usually within an integrated steel works. Fired pellets are hard iron bearing balls that are produced to a specific size range by forming iron concentrate into unbaked green pellets and then heat hardened these green pellets in a dedicated induration furnace.
May 25, 2019· General Application. The pelletizing tests conducted on four different iron ore concentrates were intended to provide a wider base for the comparison of the quality of pellets made with extracted peat moss and the conventional method of using bentonite as a binder. The generation of the relevant data for these comparisons was planned in two ...

LKAB has six pelletizing plants: three in Kiruna, two in Malmberget and one in Svappavaara. The total capacity of the plants amounts to approximately 28 million tonnes of processed iron ore products per year. The pellets are formed. In the pelletizing plant, a clay mineral, bentonite, is added as a binder in the iron ore concentrate.
Dec 20, 2017· Sintering is a thermal process (1300–1400°C) by which a mixture of iron ore, return fines, recycled products of the iron and steel industry (mill scale, blast furnace dusts, etc.), slag-forming elements, fluxes and coke are agglomerated in a sinter plant with the purpose of manufacturing a sintered product of a suitable chemical composition ...
High-quality oxidized pellets are the basis to achieve high-efficiency utilization of vanadium–titanium magnetite (VTM) ores. Bentonite was used as a binder of VTM. The main phase composition of VTM is titanomagnetite and ilmenite. When the amount of bentonite is 1%, the compressive strength and dropping strength of VTM pellets can meet the requirements.
