process of iron ore dressing

 · The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. 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.

Iron ore mining and dressing tecscience. Ore processing or ore dressing is the separation of iron ore from gangue in order to optimize the blast furnace process In principle the undesirable gangue can never be completely separated from the iron ores during ore dressing This means that a certain amount of unwanted elements always enters the blast furnace process

Existing iron ore fines processing techniques are associated with high costs, high energy consumptions and high greenhouse gas emissions. Greater environmental concern in the last few years creates the need to develop greener extraction techniques. In this study, a green
