Iron ores occur in igneous, transformed, or sedimentary rocks. The most widely distributed iron-containing minerals are oxides, such as hematite (Fe 2 O 3), magnetite (Fe 3 O 4), or limonite (FeO(OH) · n H 2 O), but carbonates such as siderite (FeCO 3) are also important.. The total iron content in iron ore plays a central economic role for mining companies.

The influence of iron ore characteristics on FeO formation during sintering was examined mainly in terms of chemical composition and the melting characteristics of iron ores. Statistical regression and X-ray diffraction were used to further explain the specific effect of iron ore characteristics on FeO formation.
This leads to a gradual increase in the formation of low melting point substances such as FeO-SiO 2, 2FeO-SiO 2 -FeO, 2FeO-SiO 2 -Fe 2 O 3, and 2FeO …
This review summarizes the studies of critical parameters to determine the kinetics of reduction. The variables considered were temperature, iron ore type …

As a key thermal-state indicator of the iron ore sintering process, the content of ferrous oxide (FeO) in the finished sinter is directly related to product quality. Based on the massive data of sintering process, the data-driven soft sensor model provides a good choice for real-time FeO content detection. However, the complex characteristics of the data, including …
FeO is an indicator of the thermal state of the sintering process and is employed as a quality control tool at many plants. Laboratory pot sinters were made, and the variation in FeO was affected by varying the amount of coke breeze in the green mix from 55 to 85 kg t −1 of sinter. The produced sinters were evaluated with respect to ...

For example, iron forms several oxides, including iron(II) oxide or wüstite (FeO), iron(III) oxide or hematite (Fe 2 O 3), and finally, iron(II,III) oxide or magnetite (FeO·Fe 2 O 3 or Fe 3 O 4). These oxides form by thermochemical reactions which depend on, and influence, their environment by producing or absorbing heat.
The iron oxide (FeO) content had a significant impact on both the metallurgical properties of sintered ores and the economic indicators of the sintering process. Precisely predicting FeO content possessed substantial potential for enhancing the quality of sintered ore and optimizing the sintering process. A multi-model integrated …
