Extraction of Iron & Concentration of Ore - An Overview

23-09-2019· These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke. Coke is cheap and it provides both the reducing agent and heat source for the reaction. The most commonly used iron ores are Hematite, Fe2O3 , and magnetite Fe 3 O 4. The process of extraction of iron and their separation is followed by three major steps: Concentration of Ore; Extraction of Iron from its concentrated ore; Purification of Iron
