The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low Agglomeration is the process of converting iron ore fines into easily handled size and shapes as required in blast furnaces [1].

The iron ore dust and SO2 originating from the industry processing activities can interfere with the vegetation of the adjacent ecosystems at various levels. An iron ore pelletizing plant in southeastern Brazil exposes the tropical coastal ecosystems known as restinga to emissions of dust, iron solid particulate matter, and sulfur dioxideThe transformation from traditional iron- and steelmaking technologies to green H2-based new technologies will require an improvement in the quality and purity of iron ore burden materials.

To utilize the iron ore fines in blast furnace and direct reduced iron plants, fines are converted to a sized spherical balls called pellets and the process is called pelletization [2][3] [4] [5The running pellet plant of capacity 4.0 MTPA is using 1.0% by weight anthracite coal fines as additives during the pelletization of hematite iron ore concentrate. The particle size distribution, along with the assay values of the iron ore fines, was calculated by standard sieving and chemical analysis method.Alleviating dependency on fossil fuel by using cow-dung during iron ore

1. Introduction. Iron ore pellets are an essential part of the blast furnace charge, with high grade, good strength, uniform particle size, good metallurgical properties, and so forth. 1,2 Especially, fluxed iron ore pellets have better high-temperature soft fusion performance and reduction performance. 3−5 However, the burden of the blast furnace is ABSTRACT. The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet.Iron Ore Pelletization: Part I.

An integrated steel plant plays an important role in India’s economic growth with a positive impact on country’s GDP. The contribution of iron and steel sector towards India’s GDP is around 2% which is quite high [].India is the second largest producer of crude steel after China with a market share of almost 6% [].India has produced around 111.2 1. Introduction. The iron and steel industry accounts for >7% (IEA, 2020) of the global greenhouse gas (GHG) emissions, of which the energy-intensive ironmaking process (crucial to primary steelmaking) contributes the vast majority.Further, the share of primary steelmaking (steel produced from iron ore) in global steel output exceeds 80%, Comparative life cycle assessment of natural gas and coal
