The chemical composition of slag 1,7 can vary over a wide range depending on the nature of the ore, the composition of the limestone flux, the coke consumption and the kind of iron being made. It can also change over the years with alterations in the sources and types of ore being smelted. These variations affect the relative content of the four major constituents: lime, silica, alumina and

Iron Ore Pelletizing Process: An Overview

2018-7-17  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.

Iron Ore Pelletizing Process: An Overview IntechOpen

2018-7-11  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-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process

2014-5-9  Step 1: Smelt the iron ore to get pig iron. Mix iron ore and coke. Coke is a fuel here. Smelt the mixture in a blast furnace to get elemental iron by heating it. Smelting is the process of extraction of metal from its ore through heating. Smelting of coke produces carbon monoxide, which in turn reduces the iron ore to elemental iron.
