Iron Ore Agglomeration Technologies | IntechOpen

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 ...

Heap Leaching Agglomeration

Some of the oxidized ore contains no clayey material, and crushing it generates very few fines. Only 6 pct of the material is minus 200 mesh. Consequently, it does not require a cement binder for agglomeration. This portion of the ore is agglomerated with cyanide solution to start the leaching process during heap building.
