Dec 17, 2020 Flotation is more to separate fine to particulate magnetic iron ore (particle size 0.02 mm). Gravity separation and magnetic separation are mainly used to separate coarse-grained and medium-grained weakly magnetic iron ore (20~2 mm). During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation of coarse and very coarse ( 20 mm) ores;

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 2.7t/m3). Gravity separation is a method of separating iron ore from impurities on the basis of the difference in their specific gravities. Gravity separators include jig
