bentonite in iron ore processing

Iron Ore Processing

About 16 pounds of Bentonite are added to every ton of iron ore concentrate. Small amounts of limestone (1%) are also added and mixed with the concentrate at this point. Limestone is added to meet the requirements of steel customers in the blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series .
