Mar 19, 2008· Iron ore, its beneficiation and agglomeration as required for iron and steel industry: A. Iron Ore: A naturally occurring mineral from which iron (Fe) metal is extracted in various forms viz Hot metal/ DRI etc.. B. Types of Ore: Two major varieties used for iron making are Haematite Ore ( containing Ferric Oxide Fe2O3) and Magnetite Ore (containing FerroFerric Oxide – Fe3O4).
Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium.

This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and the beneficiation.
As we know, the innovative process named composite agglomeration process (CAP) has a series of advantages compared to traditional sintering process (TSP). In CAP, part or all of the ironbearing dusts is made into green pellets with 5–15mm in diameter, while the rest of ironbearing dusts and all of the other fine ores is granulated after mixing with fuels, fluxes and return fines.
Sintering of Iron Ore Our quality limestone and burnt products with optimized size distribution impacts the environmental footprint of the mill by improving the sinter productivity and reducing overall energy cost and emissions.
The merits of sintering process are listed below in comparison to iron ore pellets: (i) The sintering process uses cheep coke breeze as fuel while pellets need expensive oil for firing. (ii) It is possible to agglomerate finer ore particles by sintering process without any ore grinding step as needed by pelletising technique.
The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger agglomerates. A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant.
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
The sintering process converts finesized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of .
The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2.
