    What's The Process Of Iron Smelting Meetyou Carbide

    May 18, 2017 Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration.Generally, iron ore with a grade of less than 50 needs to go through a dressing process before it can be sent to smelting for utilization. After the mined ore goes through the processes of crushing and grinding, magnetic separation, flotation and gravity separation, the high grade concentrate is obtained.At present, the iron ore resources are decreasing day by day.
