Ferrous Metals | Science Trends

Once the iron has melted, the molten slag (ash from the coke, limestone flux, and the compounds that have been formed by the reaction to the flux with all the different substances in the ore) floats on top of the iron liquid, which is heavier.

Limestone – Its Processing and Application in Iron and ...

The first process takes place at limestone mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore. In the iron and steel plant, in some of the places, raw limestone is further processed. Example is sinter plant where the raw limestone is crushed in hammer mills to – 3 mm size (generally in the range of 85 % to 90 %).

What is the purpose of limestone in a blast furnace? - …

Limestone is the reducing agent, without limestone the iron ore i.e Fe2O3 will never get reduced to Pig iron i.e Fe .. "calcination" should be lesser inside the blast furnace to reduce the coke rate that's why sinter is being used nowadays, as in sintering process limestone is calcinised

The limestone combines with the rock and other impurities in the ore to form a slag which is lighter than the iron and floats on top. As the volume of the charge is reduced, more is continually added at the top of the furnace. The iron and slag are drawn off separately from the bottom of the furnace. The melted iron might go to a further alloying process, or might be cast into ingots called ...
