Process Of Gravity Separation Of Iron Ore
1) Gravity separation The true specific gravity of iron ore is approximately 5t/m3 and is quite different from the specific gravities of major impurities such as silica and alumina (approximately 27t/m3) Gravity separation is a method of separating iron ore from impurities on the basis of the difference in their specific gravities The REFLUX ...
