    Direct Reduced Iron And Its Production Processes – Ispatguru

    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.Tunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 99.9 purity. When iron ore is mined or processed (in a crusher), lots of fines are generated. Quantity of fines generation is a function of the quality of ore i.e. whether it is hard or soft.
